TechReviewSource.com takes a look at Apple iOS 6

iOS 5 was a significant upgrade to Apple's mobile operating system that added numerous long sought-after features, such as computer-free setup, wireless syncing, and a fresh take on notifications that took inspiration from its Android competition. iOS 6 (free) isn't as game-changing, but it adds numerous features (such as a new Passbook app, a revamped Maps app, and new accessibility options) that make it a must-have download if you own a compatible device: iPhone 3GS, iPhone 4, iPhone 4S, iPod touch (4th Generation), iPad 2, and new iPad (3rd Generation) . It will also be the operating system for the iPhone 5 . But some features aren't available on all devices either due to hardware limitations or because they're specific to iPhones or iPod touches.

If iOS 5.1 is already installed on your iPad, iPhone, or iPod touch, you can update to iOS 6 either over-the-air or via iTunes. If you have a new device, there are three set up options: "Set Up as New," "Restore from iCloud Backup," and "Restore from iTunes Backup." The first option is for people who are brand new to iOS (or existing users who want a fresh start); the other two options recover previously backed up data and are what existing iPhone, iPad, and iPod touch owners will likely choose.
