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 OS 1
iPhone OS 1 is the first major release of iOS, Apple's mobile operating system. iPhone OS 1.1.5 is the latest and the last version of Apple's iPhone OS 1. This version of iOS was the first iteration of the touch-centric mobile operating system. No official name was given on its initial release; Apple marketing literature simply stated that the iPhone runs a version of Apple's desktop operating system, macOS, then known as Mac OS X. On March 6, 2008, with the release of the iPhone software development kit (iPhone SDK), Apple named it "iPhone OS" (they later went on to rename it "iOS" on June 7, 2010). It was succeeded by iPhone OS 2 on July 11, 2008.
