I know there have been similar threads, but thhey never really answered the question. My friend's iPod Touch 2g, 16GB, 3.0 is jailbroken. He has a lot of notes, calender, contacts, saved game information etc., And he wants it back to non-jailbroken. He really doesn't want to lose all his stuff, so I thought I would back it up, restore it and then restore the backup. Will there be any problems, restoring non jailbroken iPod with backup that was made when it was jailbroken? Will it leave any traces? I don't really care if there's some memory lost (unreachable), or if there's some files left over that got backed up, that i'll never even know they're there. Thanks!
