I jailbroke my iPod as soon as it came out, and have never upgraded it since. I'm sorely tempted to do so now, what with the app store and all. But i had a few questions. 1) Will any of my current freeware apps work? 2) Is there a way to restore my ipod to 1.1.1 again should I want to? 3) Is there a way to upgrade without restoring? Thank you all in advance!
