The feature originally required a Wi-Fi network, but now[when?] can use the cellular data network if one is not available.


The iPhone includes software that allows the user to upload, view, and email photos taken with the camera.




 The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari.



 The Camera application also lets users view the camera roll, the pictures that have been taken with the iPhone's camera. 
Those pictures are also available in the Photos application, along with any transferred from i Photo or Aperture on a Mac, or Photoshop on a Windows PC.

Multimedia

Multimedia
The layout of the music library is similar to that of an iPod or current Symbian S60 phones.


 The iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes.




 The iPhone uses a large view that allows users plenty of room to touch their selection.



Users can rotate their device horizontally to landscape mode to access Cover Flow.




 Like on iTunes, this feature shows the different album covers in a scroll-through photo library. 

Scrolling is achieved by swiping a finger across the screen. 

Alternatively, headset controls can be used to pause, play, skip, and repeat tracks. On the iPhone 3GS, the volume can be changed with the included Apple Earphones, and the Voice Control feature can be used to identify a track, play music songs in a playlist or by a specific artist, or create a Genius playlist.



The iPhone supports gap less playback.


 Like the fifth-generation iPods introduced in 2005, the iPhone can play digital video, allowing users to watch TV shows and movies in widescreen. Double-tapping switches between widescreen and full screen video playback.


The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone.

To make a call,



 the iPhone presents a number of options; including FaceTime on supported models. The screen is automatically disabled when held close to the face.


The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. For example, if music is playing when a call is received, the music fades out, and fades back in when the call has ended.



The proximity sensor shuts off the screen and touch-sensitive circuitry when the iPhone is brought close to the face, both to save battery and prevent unintentional touches.


 The iPhone does not support video calling or videoconferencing on versions prior to the fourth generation, as there is only 1 camera on the opposite side of the screen.

The iPhone four supports video calling using either the front or back camera over Wi-Fi, a feature Apple calls FaceTime.

 The first two models only support voice dialing through third-party applications.

 Voice control, available only on the iPhone 3GS and iPhone four, allows users to say a contact's name or number and the iPhone will dial.



The iPhone includes a visual voicemail (in some countries) feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail.


 Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list.


A music ringtone feature was introduced in the United States on September five, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee.


 The ringtones can be three to thirty seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, or loop continuously.

 All customizing can be done in iTunes, or alternatively with Apple's GarageBand software 4.1.1 or later (available only on Mac OS X)or third-party tools.

With the release of iOS 6.0, which will be released in Fall 2012, Apple plans to release features that enable the user to have options to decline a phone call when a person is calling them.


 The user will have the capability to reply with a message, or to set a reminder to call them back at a later time.


On September twelve, 2012, Apple unveiled the iPhone fifth and the sixth iteration of the iPhone.

Included items

Included items


The contents of the box of an iPhone 4. From left to right: iPhone four in plastic holder, written documentation, and (top to bottom) headset, USB cable, wall charger.




All iPhone models include written documentation, and a dock connector to USB cable. The original and 3G i Phones also came with a cleaning cloth.

 The original iPhone included a stereo headset (ear buds and a microphone) and a plastic dock to hold the unit upright while charging and syncing.

 The i Phone 3G includes a similar headset plus a SIM eject tool (the original model requires a paperclip). 


The iPhone 3GS includes the SIM eject tool and a revised headset, which adds volume buttons (not functional with previous iPhone versions).

The iPhone 3G and 3GS are compatible with the same dock, sold separately, but not the original model's dock.


 All versions include a USB power adapter, or "wall charger," which allows the iPhone to charge from an AC outlet.

 The iPhone 3G and iPhone 3GS sold in North America, Japan, Colombia, Ecuador, or Peru include an ultra compact USB power adapter.



 iOS and iOS version history


The default Home screen of iOS 5.0.1 shows most of the applications provided by Apple. Users can download additional applications from the App store, create Web Clips, rearrange the icons, and create and delete folders.


The iPhone, iPod Touch and iPad run an operating system known as iOS (formerly iPhone OS). It is a variant of the same Darwin operating system core that is found in Mac OS X.

 Also included is the "Core Animation" software component from Mac OS X v10.5 Leopard. Together with the Power VR hardware (and on the iPhone 3GS, Open GL ES 2.0), it is responsible for the interface's motion graphics. The operating system takes up less than half a gigabyte.


It is capable of supporting bundled and future applications from Apple, as well as from third-party developers.


 Software applications can not be copied or be duplicated directly from Mac OS X but must be written and compiled specifically for iOS.


Like the iPod, the iPhone is managed from a computer using iTunes. The earliest versions of the OS required version seven point three or later, which is compatible with Mac OS X version 10.3.9 Panther or later, and 32-bit Windows XP or Vista.

 The release of iTunes seven point sex  expanded this support to include 64-bit versions of XP and Vista, and a workaround has been discovered for previous 64-bit Windows operating systems.[128]



Apple provides free updates to the OS for the iPhone through iTunes,[125] and major updates have historically accompanied new models.

 Such updates often require a newer version of iTunes — for example, the three point zero update requires iTunes eight point zero — but the iTunes system requirements have stayed the same. Updates include bug fixes, security patches and new features.

 For example, iPhone 3G users initially experienced dropped calls until an update was issued.

Version three point zero required iTunes nine point zero, and iOS four  required iTunes nine point zero iTunes 10.5, which is required to sync and activate iOS 5, the current version of iTunes, Requires Mac OS X 10.5.8 or Leopard on G4 or G5 computers on 800 MHz or higher; versions 10.3 and 10.4 and 10.5–10.5.7 are no longer supported.


Interface

The interface is based around the home screen, a graphical list of available applications. iPhone applications normally run one at a time (not including iOS four  and iOS five, which includes running applications in the background),[133] although most functionality is still available when making a call or listening to music. The home screen can be accessed at any time by a hardware button below the screen, closing the open application in the process.



By default, the Home screen contains the following icons: Messages (SMS and MMS messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Voice Memos, Notes, Clock, Calculator, Settings, iTunes (store), App Store, (on the iPhone 3GS and iPhone four) Compass, Face Time and Game Center were added in iOS 4four point zero and 4.1 respectively. 



In iOS 5, Reminders and Newsstand were added, as well as the iPod application split into separate Music and Videos applications.


 iOS 6 added Passbook as well as an updated version of Maps that relies on data provided by Tom Tom as well as other sources. 

iOS six also added a Clock application onto the iPad's home screen. Docked at the base of the screen, four icons for Phone, Mail, Safari (Internet), and Music delineate the iPhone's main purposes.[135] On January 15, 2008, Apple released software update 1.1.3, allowing users to create "Web Clips", home screen icons that resemble apps that open a user-defined page in Safari. After the update, iPhone users can rearrange and place icons on up to nine other adjacent home screens, accessed by a horizontal swipe.


Users can also add and delete icons from the dock, which is the same on every home screen. Each home screen holds up to sixteen icons, and the dock holds up to four icons.


 Users can delete Web Clips and third-party applications at any time, and may select only certain applications for transfer from iTunes. Apple's default programs, however, may not be removed. The 3.0 update adds a system-wide search, known as Spotlight, to the left of the first home screen.


Almost all input is given through the touch screen, which understands complex gestures using multi-touch. 

The iPhone's interaction techniques enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, a gesture known as "pinching the screen".


Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice-versa to go back.

 In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of a real object.

Other user-centered interactive effects include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side. Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program, but always follow a consistent style motif. In menu hierarchies, a "back" button in the top-left corner of the screen displays the name of the parent folder.

Storage and SIM

Storage and SIM


An iPhone 3G with the SIM slot open. The SIM ejector tool is still placed in the eject hole.
The iPhone was initially released with two options for internal storage size: four  GB or eight GB.

            On September 5, 2007, Apple discontinued the 4 GB models.[93] On February 5, 2008, Apple added a 16 GB model.

       The iPhone 3G was available in 16 GB and 8 GB. The iPhone 3GS came in 16 GB and thirty two GB variants and remained available in 8 GB until September 2012, more than three years after its launch.


The iPhone four is available in sixteen GB and thirty two GB variants, as well as a newly introduced 8 GB variant to be sold along side the iPhone 4S at a reduced price point. The iPhone 4S is available in three sizes: 16 GB, 32 GB and 64 GB. All data is stored on the internal flash drive; the iPhone does not support expanded storage through a memory card slot, or the SIM card. 



The iPhone 5 is available in the same three sizes previously available to the iPhone 4S: 16 GB, 32 GB, and 64 GB.


GSM models of the iPhone use a SIM card to identify themselves to the GSM network.

 The SIM sits in a tray, which is inserted into a slot at the top of the device. The SIM tray can be ejected with a paperclip or the "SIM ejector tool" (a simple piece of die-cut sheet metal) included with the iPhone 3G and 3GS.


 Some iPhone models shipped with a SIM ejector tool which was fabricated from an alloy dubbed "Liquid metal".


 In most countries, the iPhone is usually sold with a SIM lock, which prevents the iPhone from being used on a different mobile network.


The GSM iPhone 4 features a Micro SIM card that is located in a slot on the right side of the device.



The CDMA model of the iPhone four, just the same any other CDMA-only cell phone, does not use a SIM card or have a SIM card slot.



An iPhone 4S activated on a CDMA carrier, however, does have a SIM card slot but does not rely on a SIM card for activation on that CDMA network. 


A CDMA-activated iPhone 4S usually has a carrier-approved roaming SIM preloaded in its SIM slot at the time of purchase that is used for roaming on certain carrier-approved international GSM networks only.

 The SIM slot is locked to only use the roaming SIM card provided by the CDMA carrier.

In the case of Verizon, for example, one can request that the SIM slot be unlocked for international use by calling their support number and requesting an international unlock if their account has been in good standing for the past 60 days.[101] This method only unlocks the iPhone 4S for use on international carriers.


 An iPhone 4S that has been unlocked in this way will reject any non international SIM cards (AT&T Mobility or T-Mobile USA, for example).


The iPhone five will feature the use of a nano SIM, in order to save more space for internal components.


Liquid contact indicators



All i Phones (and many other devices by Apple) have a small disc at the bottom of the headphone jack that changes from white to red on contact with water; iPhone 3G and later models also have a similar indicator at the bottom of the dock connector.

 Because Apple warranties do not cover water damage, employees examine the indicators before approving warranty repair or replacement.


The iPhone's indicators are more exposed than those in some mobile phones from other manufacturers, which carry them in a more protected location, such as beneath the battery behind a battery cover. The iPhone's can be triggered during routine use, by an owner's sweat, steam in a bathroom, and other light environmental moisture.


 Criticism led Apple to change to its water damage policy for i Phones and similar products, allowing customers to request further internal inspection of the phone to verify if internal liquid damage sensors were triggered.

Battery

Battery


Replacing the battery requires disassembling the iPhone unit and exposing the internal hardware
The iPhone features an internal rechargeable lithium-ion battery.


 Like an iPod, but unlike most other mobile phones, the battery is not user-replaceable.

 The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. 


Alternatively, a USB to AC adapter (or "wall charger," also included) can be connected to the cable to charge directly from an AC outlet. A number of third-party accessories (car chargers, portable chargers, battery cases, stereo dock chargers, and even solar chargers) are also available.

[citation needed]



Apple runs tests on pre production units to determine battery life. Apple's website says that the battery life "is designed to retain up to 80 percent of its original capacity after 400 full charge and discharge cycles", which is comparable to iPod batteries.


The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple's claims.


 This is also reflected by a J. D. Power and Associates customer satisfaction survey, which gave the "battery aspects" of the iPhone 3G its lowest rating of tow out of five stars.


If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty.


 The warranty lasts one year from purchase and can be extended to two years with Apple Care. The battery replacement service and its pricing was not made known to buyers until the day the product was launched,it is similar to how Apple (and third parties) replace batteries for iPods.




 The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced.


Since July 2007, third-party battery replacement kits have been available at a much lower price than Apple's own battery replacement features.


 These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the original iPhone has been soldered in.


 Therefore a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace.


The iPhone two is the first generation to have two cameras. The LED flash for the rear-facing camera (top) and the forward-facing camera (bottom) are both unique to that model.
Camera.


The original iPhone and iPhone 3G feature a built-in fixed focus 2.0 megapixel camera located on the back for still digital photos.


 It has no optical zoom, flash or auto focus, and does not support video recording (iPhone 3G does support video recording via third-party App available on the App Store), however jail breaking allows users to do so.

 Version two point zero of iPhone OS introduced the capability to embed location data in the pictures, producing geo coded photographs.


                          The iPhone 3GS has a 3.2 megapixel camera, manufactured by Omni Vision, featuring autofocus, auto white balance, and auto macro (up to ten cm). 

It is also capable of capturing 640 × 480 (VGA resolution) video at  thirty frames per second, although compared to higher-end CCD based video cameras it does exhibit the rolling shutter effect.


 The video can then be cropped on the device itself and directly uploaded to YouTube, Mobile Me, or other services.


The iPhone 4 introduced a five point zero megapixel camera (2592 × 1936 pixels), also located on the back, which is equipped with a backside illuminated sensor capable of capturing pictures in low-light conditions, as well as an LED flash capable of staying lit for video recording at seven hundred p resolution, considered high-definition.


 iPhone four is the first iPhone that has the high dynamic range photography feature.

 In addition the iPhone four has a second camera on the front capable of VGA photos and SD video recording.


Regardless of the source, saved recordings may be synced to the host computer, attached to email, or (where supported) sent by MMS.

 Videos may be uploaded to YouTube directly.


The camera on the iPhone four S is capable of shooting eight MP stills and recording ten thousand eighty p videos. The camera can now be accessed directly from the lock screen, and the volume up button as a shutter trigger. The built-in gyroscope is able to stabilize the camera while recording video.



Beta code pulled from iOS 5 suggests that the next feature to be released will allow users to capture a panoramic photo on their iPhone.
On all five model generations, the phone can be configured to bring up the camera app by quickly pressing the home key twice.[92] On all i Phones running iOS five it can also be accessed from the lock screen directly.

Photo browsing

 Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations.


Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so

. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input.



Furthermore, accelerometer can also be used to control third-party apps, notably games.

 The iPhone 4 also includes a gyroscopic sensor, enhancing its perception of how it is moved.


A software update in January 2008 allowed the 1st-generation iPhone to use cell tower and Wi-Fi network locations trilateration, despite lacking GPS hardware.

 The iPhone 3G, 3GS and 4 employ A-GPS, and the iPhone 3GS and four also have a digital compass. iPhone four S supports GLONASS global positioning system in addition to GPS.
Audio and output


One of two speakers (left) and the microphone (right) surround the dock connector on the base of the original iPhone. If a headset is plugged in, sound is played through it instead.



On the bottom of the iPhone there is a speaker to the left of the dock connector and a microphone to the right.

 There is an additional loudspeaker above the screen that serves as an earpiece during phone calls. The iPhone four includes an additional microphone at the top of the unit for noise cancellation, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the right.


 Volume controls are located on the left side of all iPhone models and as a slider in the iPod application.
The 3.5 mm TRRS connector for the headphones is located on the top left corner of the device.

The headphone socket on the original iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter.

 Subsequent generations eliminated the issue by using a flush-mounted headphone socket.

 Cars equipped with an auxiliary jack allow for hands free use of the iPhone while driving as a substitute for Bluetooth.


While the iPhone is compatible with normal headphones, Apple provides a headset with additional functionality.

 A multi purpose button near the microphone can be used to play or pause music, skip tracks, and answer or end phone calls without touching the iPhone.


 A small # of third-party headsets specifically designed for the iPhone also include the microphone and control button.

 The current headsets also provide volume controls, which are only compatible with more recent models.

 These features are achieved by a fourth ring in the audio jack that carries this extra information.


The built-in Bluetooth two.x+EDR supports wireless earpieces and headphones, which requires the HSP profile.

 Stereo audio was added in the 3.0 update for hardware that supports A2DP.

 While non-sanctioned third-party solutions exist, the iPhone does not officially support the OBEX file transfer protocol.


The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other blue tooth-enabled cell phones.



Composite or component video at up to five hundred and six i and stereo audio can be output from the dock connector using an adapter sold by Apple.


 iPhone 4 also supports 1024 × 768 VGA output without audio, and HDMI output, with stereo audio, via dock adapters. The iPhone did not support voice recording until the 3.0 software update.

Fast food takeaways are eventually an expensive way to damage your health!

What does 22,000 cases of cancer cost the NHS (us)?
 What is the annual Government budget to truly diagnose and carry out clinical trials on everything we eat?

 How many time and effort is spent from our earliest school days into adulthood to educate us into healthy eating and avoidance of obesity? 

Nutrition should have a far greater spend by the NHS as opposed to trying to treat cancer once it has taken its hold.

 Why is it that only man in this animal kingdom eats and drinks the milk of another animal?

 Think of going dairy free, forget processed supermarket foods with all their additives and get back to basics of vegetable stews, pulses and juicing vegetables.

 Fast food takeaways are eventually an expensive way to damage your health! In most cases obesity is simply down to what you eat, so eat and drink badly and potentially die sooner.

 Do not 'diet' but just simply change your diet.


It frightens me how incorrect the government and NHS Nutritional advice is here.

 Grains (Particularly the Wheat), Polyunsaturated fat and high fructose from sources other than fruit are the main culprits for the terrible rates of heart disease, cancer, diabetes and the countless other diseases of modern age.

 Grains and Polyunsaturated fat have been shown to raise triglycerides, lower HDL, Raise (sd)LDL and (lb)LDL - BAD.

Saturated and Monounsaturated fat have been shown to Lower Triglycerides, lower HDL, Raise (sd)LDL and raise (lb)LDL (lbLDL is benign). 

Oxidation and inflammation are your enemies and the recommended plate above will lead you to it.

 Just because lots of people (Including the NSH and government) say a certain way of eating is right doesn't actually make it the right.



As an independent dietitian, I would like to clarify a number of issues that have been raised in relation to the Eat the plate of good food .

There are a large variety of both wholegrain and white products identified in the yellow starch section and the text promotes and encourages the choice of wholegrain varieties to individuals.


The size of all the sections (including the yellow starch section) is based on scientific evidence developed for the independent Nutrition Task Force.

 This took into account data produced for the Committee on Nutritional Aspects of Cardiovascular Disease and Dietary Reference Values.


The evidence base for low carbohydrate diets (20-40g per day) shows that their long-term health effects (of over 1 year) are unknown in terms of heart, kidney and health of bones.

 Same as it, cancer risk is unknown, especially in those who are obese, so they are not recommended.

Starchy foods of all types are important contributors of protein, iron, calcium and vitamin B complex in particular in our diet.

what is a joke

Eventually, a humor is something spoken, written, or done with joking intention.

 Jokes may have many different ways to express and their different  forms, e.g., a single word or a gesture (considered in a particular context), a question-answer, or a whole short story.

 Infect, the word "joke" has a number of synonyms, including wisecrack, gag, prank, quip, jape and jest.

To achieve their end, jokes may employ irony, sarcasm, word play and other devices.

 Jokes may have a punch line, i.e. an ending to make it humorous or funny.

A practical joke or prank differs from a spoken joke in that the major component of the humor is physical rather than verbal (for example placing salt in the sugar bowl).


Jokes are typically for the entertainment of friends,coworkers and onlookers.

 The desired response is generally laughter; when this does not happen the joke is said to have "fallen flat" or "bombed".

 Furthermore, jokes have other purposes and functions, common to comedy/humor/satire in general.

Picture browsing

Picture browsing, website browsing, and music playing support both upright and left or right widescreen orientations.


Unlike the iPad, the iPhone does not rotate the screen when turned upside down, with the Home button above the screen, unless the running program has been specifically designed to do the same.

made of plastic

All buttons except Home were made of plastic on the original iPhone and metal on all later models.

 The touch screen furnishes the remainder of the user interface.

The display responds to three sensors (four on the iPhone 4).

 A proximity sensor deactivates the display lights and touchscreen when the device is brought near the face during a call.

 This is done to save battery power and to prevent inadvertent inputs from the user's face and ears.

 An ambient light sensor adjusts the display brightness which in turn saves battery power which is an effective function for your phone.

 A 3-axis accelero meter senses the orientation of the phone and changes the screen accordingly, allowing the user to an easily switch between portrait and landscape mode.

Five Buttons of iPhone

The iPhone has a minimal hardware user interface, featuring five buttons.

 Eventually only the physical menu button is situated directly below the display, and is called the "Home button" because it closes the active applications  and navigates to the home screen of the interface.

 The home button is denoted not by a house, as on many other similar devices, but a rounded square, reminiscent of the shape of icons on the home screen.

A  several function sleep/wake button is located on the top of the phone.
 It serves as the unit's power button, and also controls phone calls. 
When a call is received, pressing the sleep/wake button once silences the ringtone, and when pressed twice transfers the call to voice-mail. 

Situated on the left spine are the volume adjustment controls button. 
The iPhone 4 has two separate circular buttons to increase and decrease the volume; all earlier models house two switches under a single plastic panel, known as a rocker switch, which could reasonably be counted as either one or two buttons.

Directly above the volume controls is a ring/silent switch that when engaged mutes telephone ringing, alert sounds from new & sent emails, text messages, and other push notifications, camera shutter sounds, Voice Memo sound effects, phone lock/unlock sounds, keyboard clicks, and spoken auto correction speakers indeed.
 This switch does not mute alarm sounds from the Clock application, and in some countries or regions it will not mute the camera shutter or Voice Memo sound effects.

gesture features of an iPhone

The touch screen and gesture features of an iPhone are based on technology originally developed by Finger Works.

Most gloves and styli prevent the necessary electrical conductivity however, capacities styli can be used with iPhone's finger-touch. 

The iPhone 3GS and later also feature a fingerprint-resistant oleo phobic coating.

screen input of iPhone 5

Screen and input
The touchscreen on the first five generations is a 9 cm (3.5 in) liquid crystal display and glass is available with scratch-resistant glass, while the one on the iPhone 5 is 4 inches.


The capacity touchscreen is designed for a bare finger, or multiple fingers for multi-touch screen sensing.

The screens on the first three generations have an amazing resolution of 320 × 480 (HVGA) at 163 ppi, while those on the iPhone 4 and iPhone 4S have a resolution of 640 × 960 at 326 ppi.

History of the iPhone
Development of what was to become the iPhone began in 2004, when Apple started to gather a team of 1000 employees to work on the highly confidential "Project Purple". Apple CEO Steve Jobs steered the original focus away from a tablet, like the iPad, and towards a cell phone. Apple created the device during a secretive collaboration with AT&T Mobility—Cingular Wireless at the time—at an estimated development cost of US$150 million more then thirty months.
Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house and even paid Apple a fraction of its monthly service revenue unitill the iphone 3G, in exchange for four years of exclusive U.S. sales, until 2011.
Jobs unveiled the iPhone to the public on January 9, 2007, at the Macworld 2007 convention at the Moscone Center in San Francisco. The two initial models, a 4 GB model price was US$ 499 and a 8 GB model was US$ 599, went on sale in the United States on June 29, 2007, at 6:00 pm local time, while hundreds of customers lined up outside the stores nationwide. The passionate reaction to the launch of the iPhone resulted in sections of the media christening it the 'Jesus phone'. The original iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in the spring of 2008.

On July 11, 2008, Apple released the iPhone 3G in 22 countries, including the original 6. Apple released the iPhone 3G in upwards of eighty countries. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. Many would-be users objected to the iPhone's cost, and 40% of users have household incomes over US$100,000.
Apple sold 6.1 million original iPhone units over five quarters. Recorded sales have been growing rapidly thereafter, and by the end of fiscal year 2010, a total of 73.5 million iPhones were sold. By 2010/2011, the iPhone had a market share of barely 4% of all cellphones, but Apple still pulls in more than 50% of the total profit that global cell phone sales generate. Sales in Q4 2008 surpassed temporarily those of Research In Motion's (RIM) BlackBerry sales of 5.2 million units, which made Apple briefly the third largest mobile phone manufacturer by revenue, after Nokia and Samsung. Approximately 6.4 million iPhones are active in the U.S. alone. While iPhone sales constitute a significant portion of Apple's revenue, some of this income is deferred,

Over 1 million 4S models were sold in the first 24 hours after its release in Oct 2011. Due to large volumes of the iPhone being manufactured and its high selling price, Apple became the largest mobile handset vendor in the world by revenue, in 2011, surpassing long-time leader Nokia. American carrier C Spire Wireless announced that it would be handle the iPhone 4S on October 19, 2011.

The average selling price has remained fairly constant for most of the phones lifespan, hovering between $622 and $660. The production price of the iPhone 4S was estimated by IHS iSuppli, in October 2011, to be $188, $207 and $245, for the 16GB, 32GB and 64GB models, respectively. Labor costs are estimated at between $12.5 and $30 per unit, with workers on the iPhone assembly line making $1.78 an hour.[47]

iphone 4 tip

If you want to ignore auto correction while you  messaging  just write Z  at the end, auto  correction function will not work try it now.
It really works i have personal experience with this... 

Save you time and try these helpful tips

Lots of advance features get added to iOS  that we often don’t take benefits of them all. The very recent iOS 5.0 and 5.1 updates for iPhone iPad, or iPod touch users make the devices very easier to handle it several helpful features for the iPhone camera, and perhaps known preference options in the Settings parts.

I have  chosen ten of my favorites, but I’m sure I’ve overlooked all please comment on it if you know more tips write it here

Deleting Apps

You might find  that a quick way to delete several apps at your iOS 5 device is to launch the Settings app and tap Usage. From there you will get a list of all your apps and their file size. Tap on each apps you want to delete, and touch the Delete App button.

Quick Camera Access

The  iOS 5 update, the Camera app can be accessed by the Lock screen, but instead of tapping at Camera app, which causes a delay in activation, slide it upward  for quicker access to the camera, if you’re taking a photo in landscape position, just press the volume-up button on the iPhone to activate the shutter. (The button works in portrait mode also, but I find it more cumbersome to use in that position.)

Folder In Dock

If you have a folder of apps that you use very  often, you might consider putting it in your device’s Dock as you can with individual apps. This is very useful for the iPhone and iPod touch which of course have a lot less screen real-estate than the iPad.

Keyboard Shortcuts

If you are  not using keyboard shortcuts on your device, you’re missing out on a great time-saving feature. Open Settings > General, and scroll down to Keyboard > Shortcuts. Tap the upper-right + button and add a phrase, name, or regularly used word, and then assign it a shortcut. Be sure to a use a combination of letters that don’t make up the first few letters of a real word.

You probably should keep your shortcuts to 2-4 letters to make them easier to remember.

the shortcut cannot be the same as an exiting shortcut 

When you type a shortcut in a text box, the assigned phrase or word will pop-up and you will touch  that pop up to insert that

Ideas for shortcuts include your first and last name, your email address, causally  used text messages, and tags used in social networking sites.


Turn Off Automatic App Download


I don’t know about you, but most of the apps I download on my iPad are often not ones I use on my iPhone The iOS 5 update – I believe by default – automatically downloads your app purchases to all your iOS supporting devices. If this a problem for you, simply launch the Settings app, scroll down to Store, and turn off automatic downloads for Apps.

Notifications

By Settings you can also touch on Notifications to manage the types of notifications you want for individual apps. From there you can tap the Edit button to re-arrange the order of app notifications in Notification Center.

You can tap on each individual app and select the type of notifications you want to open, or disable notifications all .

Scroll down the page and add apps to your Notifications Center that are not there.

iPhone camera app, you can enlarge subject by pinching on the screen with two fingers to bring up the 5x digital zoom. Note however, this is digital zoom, which works like a magnifying glass, rather than optical zoom. So the subjects you zoom in on won’t be as sharply focused. But it’s still a handy feature for when you need it.

Turn Off Camera Grid

if grid overlay in the Camera app annoys you while taking pictures, simply tap on the Options button on the screen to turn it off. Or better yet learn how to use the grid to compose and/or crop photos.

Create A Playlist

create playlists in iTunes, you can also make  on-the-go playlists in the iOS 5 Music App. To do so, launch the app and touch on “Add Playlist….” Create a title for the playlist, tap save, and from there tap to add individual songs from your Music library to create your list.

Use Flipboard

This is not a native iOS tip, but if you haven’t, download the free RSS feed magazine app Flip board for your device, especially for the iPad. This app provides a much better experience of viewing your Twitter, Facebook, and Instagram streams.
