Trying to update my Ipad2 to IOS 6 but do ot have a "software update" button in the system/general screen.
If you are running an iOS level prior to iOS 5 you will not have the Software Update feature. You will have to connect to iTunes on your computer to do the update.
If your machine isn't already running iOS5, you need to plug it into your computer and use iTunes to download the update.
And for iOS 6 you need iTunes 10.7 or 11 on your computer.
