Apple has released an update to iOS5. It’s primary purpose seems to be to deal with the dreaded battery drain issue that many people are experiencing. But another aspect of this update that is significant is that it is the first over-the-air iOS update available. If you go to Settings | General | Software Update you can download the update straight to your iPhone or iPad without connecting to iTunes. But, to be honest, it is not exactly wireless – the update wants you to connect to power during the download and update to prevent problems. This is standard stuff on laptop updates too so it is really no surprise and I suggest you heed the warning. But being able to update devices without connecting to iTunes will be a nice feature.
So go forth and update!
