I've had a jailbroken iPod Touch 2nd gen for quite some time now, and in anticipation of upgrading to the 4th gen (when it comes out) or the iPhone 4g I had a question. I realize that when those devices come out their won't be a jailbreak for several months at least. What I want to know is if I can load a backup of my current iPod Touch onto a new one and keep all my save game data. Will it not be able to restore because it is a jailbroken back up? And if so, is there a way to obtain a "clean" back up? Normally I would use AppBackup, but seeing as the new devices won't have jailbreaks that isn't really an option. I just don't want to lose all my save data. Any answers/ideas?
