iOS 6 is finally available for public consumption and you can get it one of two ways: You can plug your iOS device in to your computer and check iTunes for an update, or you can go into the settings menu on your iPhone 3GS, 4 or 4S, iPod touch 4G, 5G or iPad iPad 2 or New iPad and navigate to General > Software Update. And while updating shouldnt wipe out your previously stored data, you should back your device up just to be safe. And if you dont see the update popping up right away, just give it a minute. These things can sometimes take a while when first rolling out.
It's my life, you're just along for the ride!
