My non-jailbroken iPhone 4S needs to go for a warranty repair, and I want to restore its data to an older non-jailbroken 3G or to another even older jailbroken 2G, but of course itunes refuses to comply :). Is there a way to do this "innocent" operation? Thanks a lot
Since the iPhone 3G and iPhone 2G run an iOS version that doesn't match what's on the 4S, iTunes would not allow this. You would either have to get an iPhone 4S on loan to restore your current data or just have iTunes retain the backup of the device being sent for repair until you get it back.
