A Full Guide on How to Update iPhone with/without iTunes

Part 1: Which iPhones Can Update to iOS 5, iOS6 or iOS 7

Before updating your iPhone to latest iOS version you should keep in mind that your device should support the latest iOS version.

iOS 5: supported devices

iOS 5 is only supported by newer devices. An iPhone must be an iPhone 3GS or newer. Any iPad will work. An iPod touch must be 3rd generation or newer.

iOS 6: supported devices

iOS 6 is only supported on iPhone 4S or newer. Any iPad will work. An iPod touch must be 5th generation. iOS 6 offers limited support for the iPhone 3GS/4.

iOS 7 supported devices

iOS 7 is only supported on iPhone 4 or newer. Any iPad will work. An iPod touch must be 5th generation.

Whichever iOS you want to upgrade to, first of all, I suggest that you should make a backup before updating the iPhone. A backup prevents you from losing any data in case something goes wonky down the line.
