iOS 5 wireless update system software

Apple has just released iOS 5 beta 4 to its developers. New in this beta is the ability to update iOS itself over-the-air directly from Apple servers without the use of cables and iTunes. InsanelyGreatMac has posted a video to demo the upgrade process from iOS 5 beta 3 to iOS 5 beta 4 wirelessly. The best part of this new mechanism is only delta changes are delivered down to your iPhone for the upgrade, saving large amount of data and time.
