As of iOS 4, Apple no longer charges for iPod Touch updates. iPhone users receive all software updates for free, while iPod Touch users paid for the 2.0 and 3.0 major software updates. Īpple concurrently provides the same version of iOS for the comparable model of iPhone and iPod Touch, usually devices released in the same calendar year. Apple licensed the 'iOS' trademark from Cisco Systems. iOS 4 was the first major iOS release that reflected the name change. The introduction of what would later become the iPad line, and the existence of iPod Touch, meant the iPhone was no longer the only device to run the mobile operating system. It was officially renamed iOS on June 7, 2010, with the announcement and introduction of the first-generation iPad. When iOS was introduced, it was named iPhone OS. Before then, Apple marketing simply stated that iPhone ran a version of Mac OS X made specifically for the iPhone. iOS did not have an official name until the official release of the iPhone software development kit ( iPhone SDK) on March 6, 2008. June 2007 saw the official release of what eventually became iOS – concurrently with the first iPhone.
