IOS



"There's an app for that."

Apple's iOS (formerly "iPhone OS") is the operating system that powers their iPhones, iPods, and iPads. It is derived from OS X, but applications are not compatible between the two, and no emulators capable of running commercial apps have been released yet. iOS is much more locked down than rival Android, and its app store is much more restrictive (no controversial or adult content, emulators, non-WebKit browsers, or GPL-licensed applications). Through a process called jailbreaking, you can bypass all of these restrictions and do anything you want with iOS.
