Iphone-Iphone Wallpaper 034: The iPhone (play /ˈaɪfoʊn/ EYE-fohn) is a line of smartphones designed and marketed by Apple Inc. The iPhone runs Apples iOS mobile operating system, originally named 'iPhone OS'. The first iPhone was released on June 29, 2007; the most recent iPhone, the sixth-generation iPhone 5, was released on September 21, 2012. The user interface is built around the devices multi-touch screen, including a virtual keyboard rather than a physical one. The iPhone has Wi-Fi and cellular connectivity (2G, 3G and 4G (iPhone 5 only)).

An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send texts, and receive visual voicemail. Other functions-games, reference, GPS navigation, social networking, etc.-can be enabled by downloading apps; as of 2012, the App Store offered more than 700,000 apps by Apple and third parties.

There are six generations of iPhone models, each accompanied by one of the six major releases of iOS (formerly iPhone OS). The original iPhone was a GSM phone, and established design precedents, such as screen size and button placement, that have persisted through all models. The iPhone 3G added 3G cellular network capabilities and A-GPS location. The iPhone 3GS added a faster processor and a higher-resolution camera that could record video at 480p. The iPhone 4 featured a higher-resolution 960 x 640 'retina display', a higher-resolution rear-facing camera and a lower-resolution front-facing camera for video calling and other apps. The iPhone 4S added an 8-megapixel camera with 1080p video recording, a dual-core processor, and a natural language voice control system called Siri. iPhone 5 features the new A6 processor, holds a 4-inch Retina display that is larger than its predecessors 3.5-inch display, and replaces the 30-pin connector with an all-digital Lightning connector.

For some years, Apple and its manufacturing contractor Foxconn have received criticism due to poor working conditions at the assembly plant in China.

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 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 over 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 iPhones hardware and software in-house and even paid Apple a fraction of its monthly service revenue (until 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 priced at US$ 499 and a 8 GB model at 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 twenty-two countries, including the original six. Apple released the iPhone 3G in upwards of eighty countries and territories. 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 iPhones 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 steadily 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 cellphone sales generate. Sales in Q4 2008 surpassed temporarily those of Research In Motions (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 Apples revenue, some of this income is deferred.

The back of the original iPhone was made of aluminum with a black plastic accent. The iPhone 3G and 3GS feature a full plastic back to increase the strength of the GSM signal. The iPhone 3G was available in an 8 GB black model, or a black or white option for the 16 GB model. They both are discontinued. The iPhone 3GS was available in both colors, regardless of storage capacity.

The iPhone 4 has an aluminosilicate glass front and back with a stainless steel edge that serves as the antennas. It was at first available in black; the white version was announced, but not released until April 2011, 10 months later.

The iPhone has garnered positive reviews from such critics as David Pogue and Walter Mossberg. The iPhone attracts users of all ages, and, besides consumer use, the iPhone has also been adopted for business purposes.

Users of the iPhone 4 reported dropped/disconnected telephone calls when holding their phones in a certain way. This became known as antennagate.

On January 11, 2011, Verizon announced during a media event that it had reached an agreement with Apple and would begin selling a CDMA2000 iPhone 4. Verizon said it would be available for pre-order on February 3, with a release set for February 10. In February 2011, the Verizon iPhone accounted for 4.5 percent of all iPhone ad impressions[vague] in the U.S. on Millennial Medias mobile ad network. The Verizon iPhone has the Mobile Hotspot' feature, only for Verizon iPhone since that is a Verizon feature. On March 2, 2011, at the iPad 2 event, Apple announced that they had sold 100 million iPhones worldwide.

From 2007 to 2011, Apple spent $647 million on advertising for the iPhone in the United States.

On Tuesday, September 27, Apple sent invitations for a press event to be held October 4, 2011 at 10:00 am at the Cupertino Headquarters to announce details of the next generation iPhone, which turned out to be iPhone 4S. Over 1 million 4S models were sold in the first 24 hours after its release in October 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 carrying the iPhone 4S on October 19, 2011.

In January 2012, Apple reported its best quarterly earnings ever, with 53% of its revenue coming from the sale of 37 million iPhones, at an average selling price of nearly $660. 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.

In February 2012, ComScore reported that 12.4% of US mobile subscribers use an iPhone.

On September 12, 2012, Apple announced the iPhone 5. It has 4-inch display, up from its predecessors 3.5-inch screen. The device comes with the same 326 pixels per inch found in the iPhone 4 and 4S. The iPhone 5 has the soc A6 processor, the chip is 22 percent smaller than the iPhone 4S A5 and is twice as fast, doubling the graphics performance of its predecessor. The device is 18 percent thinner than the iPhone 4S, measuring 7.6mm, and is 20 percent lighter at 112 grams.
