Apple began work on the first iPhone in 2005 and the first iPhone was released on June 29, 2007. The iPhone created such a sensation that a survey indicated six out of ten Americans were aware of its release. "Time" declared it "Invention of the Year" for 2007. The completed iPhone had multimedia capabilities and functioned as a quad-band touch screen smartphone. A year later, the iPhone 3G was released in July 2008 with three key features: support for GPS, 3G data and tri-band UMTS/HSDPA. In June 2009, the iPhone 3GS, whose improvements included voice control, a better camera, and a faster processor, was introduced by Phil Schiller. The iPhone 4 is thinner than previous models, has a five megapixel camera capable of recording video in 720p HD, and adds a secondary front-facing camera for video calls. A major feature of the iPhone 4S, introduced in October 2011, was Siri, a virtual assistant capable of voice recognition.
History of iPhone
Early estimates by technology analysts estimated sales of between 250,000 and 700,000 iPhones in the first weekend alone, with strong sales continuing after the initial weekend. As part of their quarterly earnings announcement, AT&T reported that 146,000 iPhones were activated in the first weekend. Though this figure does not include units that were purchased for resale on eBay or otherwise not activated until after the opening weekend, it is still less than most initial estimates. It is also estimated that 95% of the units sold are the 8GB model.
