Hay everyone. I need some help bad, I'm trying to update the is on a ipad that's on iOS 3.2.1 but every time I plug it into the computer and back it up it just shows the loading bar at the top. I have tried deleting the backup file in iTunes and also tried leaving it over night but it still does nothing. I'm thinking the only thing that might be makeing this happen is having a few apps that are for iOS 5
