Steve Jobs
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.
IPhone 4S
Reception to the was generally favorable. Reviewers noted Siri, the new camera, and processing speeds as significant advantages over the prior model. It was succeeded by the iPhone 5 as Apple's flagship phone on September 12, 2012. The iPhone 4S remained on sale, albeit being sold with reduced storage (from 16/32/64 GB down to 8 GB). The 4S was officially discontinued on September 9, 2014 following the announcement of the iPhone 6, although production did continue for developing markets until February 17, 2016. During the course of its lifetime, the iPhone 4S was the best-selling iPhone ever produced and it is the first iPhone to support five major versions of iOS: iOS 5, iOS 6, iOS 7, iOS 8, and iOS 9 (the iPad 2 was supported from iOS 4 to iOS 9). The 4S is also the last iPhone to have the original 30 pin connector as the succeeding iPhone 5 replaced it with the all digital Lightning Connector.
