Review: Apple iOS 6
iOS 6 is no doubt the best version of Apple's mobile operating system yet. It's the most powerful, the most personal, and the most polished mobile platform available.
Though Apple has laden the OS with 200 new features, it still runs just as spritely as the first version of iOS did back in 2007 — in fact, it runs much faster. It isn't as flexible as Android, nor perhaps as modern looking as Windows Phone, but it has a look and feel that are easy to learn and manipulate.
iOS 6 might be the least revolutionary update to Apple's mobile platform, but the changes are ones needed and long in the making. iOS 6 is compatible with the iPhone 3GS, iPhone 4, iPhone 4S, and iPhone 5, in addition to the iPad 2 and iPad with Retina Display. Not all the features are available to all the devices. It is a free download from Apple.
