iPhone

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 and included it in the All-TIME 100 Gadgets list in 2010, in the category of Communication. 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 was thinner than previous models, had a five megapixel camera capable of recording video in 720p HD, and added 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.
