Is there any way to un-jailbreak without having to restore my iPod?

Well, I don't think so. :( But I'm gonna have to do the same thing for 3.0 jailbreak. I know restoring your iPod sucks but if your jailbroken and have to upgrade, it's your only option. :( But, all your apps, music, videos, and more will still be on your computer so all you'll have to do is re-sync all your stuff back. :D

So you need to un-jailbreak before upgrading to 3.0? Will you need to restore from a backup before or after the upgrade at all?

1st besure to backup your data

then just re jailbreak and when you do the shift+restore thing find the 3.0 software and boom its jailbroken 3.0
