The iOS is the operating system that runs the iPhone, iPod touch, and iPad. It's the core software that comes loaded on all devices to allow them to run and support other apps. The iOS is to the iPhone what Windows is to PCs or Mac OS X is to Macs. This article is a history of each version of the iOS, when it was released, and what it added to the platform.
