Apple announced iPhone iOS 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.
Since initial release, iOS has been updated year-on-year. In September 2019, with release of iOS 13, the OS was split between iPhone and iPad - and became iOS for iPhone and iPadOS for iPad.
The current release is iOS/iPadOS 17.2.
