In the past six years, Apple has released seven versions of iOS. iOS 7 is building up to be the biggest change to to OS since the launch of the iPhone. From the complete redesign, to features like iBeacons, AirDrop, and iTunes Radio, iOS 7 looks and feels vastly different from the original iPhoneOS.
