iPhone OS 1

iPhone OS 1 is the first major release of iOS, Apple's 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.[1][2] On March 6, 2008, with the release of the iPhone software development kit (iPhone SDK), Apple named it iPhone OS[3] (they later went on to rename it "iOS" on June 7, 2010[4]). It was succeeded by iPhone OS 2 on July 11, 2008.
