Apple has just started seeding its latest iOS 6 to iDevices around the globe. If you own a 4S, 4, 3GS or iPad 2, new iPad and iPod Touch you can expect to get the update in the following hours.
This is the first iOS release that's available over the air so you can check the Software update menu on your eligible device. You can also check for the update from your computer, but you'll need the latest iTunes (v10.7) installed.
The update might take a while depending on where you are. If you know your Apple stuff you should know that the main features in iOS 6 are the brand new Maps app with free voice-guided navigation, which replaces Google Maps, Facebook integration and a more functional Siri. Here's our iOS 6 preview if you want to check out what else has changed.
