New iOS versions are released every year alongside new iPhone models. From its launch in 2007 until 2010, this occurred in June or July, since then, new major versions are released in September or October. Since the launch of the iPhone in June 2007, there have been 16 major releases of iOS. The current major version of iOS is iOS 16, released in September 2022.

Apple announced iPhone OS 1 at the iPhone keynote on January 9, 2007, and it was released to the public alongside the first-generation iPhone on June 29, 2007.[3] No official name was given when the iPhone was released, and Steve Jobs just said "iPhone runs OS X".[4][5] During the development phase of iPhone OS 1, "probably 16, 17 different concepts" were developed. Many on the team were skeptical of the feasibility of a touchscreen keyboard, and believed that users would prefer hardware keyboards. A number of different user interfaces were prototyped, including one that involved a multi-touch click-wheel.[6]
iPhone OS 1 was criticized for its lack of support for Adobe Flash web content, copy and paste, and Bluetooth stereo headphones.[7] It also lacked support for third-party native apps, and only supported web apps,[8] which was criticized by reviewers and developers,[9][10] including John Carmack.[11]
iPhone OS 1.1 was the first version supported by the first generation iPod Touch.[12] iPhone OS 1.1.4 is the final version of iPhone OS 1 for the first generation iPhone, with iPhone OS 1.1.5 being the final version of iPhone OS 1 available for the first generation iPod Touch.[13] It was succeeded by iPhone OS 2 on July 11, 2008.[14]
