Okay so I just updated Grand Theift Auto: Vice City. Normally when I update a game of this size it downloads the whole game again. When I just updated it on my iPhone it seemed to only download the part of the game that changed then reinstalled itself. Is this new to iOS 6? I know it didn't download the full game because its over a gig and it downloaded and installed in less than 3 minutes and my Internet connection isn't that fast. Something that would normally take at least an hour.
