Releases

iPhone OS 1

Apple announced iPhone OS 1 at the iPhone keynote on January 9, 2007, and it was released to the public alongside the original iPhone on June 29, 2007.[3] No official name was given when the iPhone was released; Apple marketing literature simply stated the iPhone ran a mobile version of "OS X".[4] During the development phase of iPhone OS 1, there were at least 17-18 different concepts developed. Many on the team were still hung up on the idea that everyone would want to type on a hardware keyboard, not a glass screen. The idea of introducing a complete touch screen was very novel to everyone.[5] Many user interfaces were prototyped, including the multi-touch click-wheel. Although many thought it was a waste of time, Apple CEO Steve Jobs insisted on prototyping all concepts before the Mac OS-X-based version of the operating system was selected. The release of iPhone OS 1.1 brought support for the iPod Touch (1st generation). iPhone OS 1.1.4 is the final version of iPhone OS 1 for the iPhone, and iPhone OS 1.1.5 is the final version of iPhone OS 1 for the iPod Touch (1st generation).
