I have a jailbroken 3G 32GB I'm selling it the way it is, apps and all. I've cleared it as much as i can without actually restoring it or resetting it, but I can't seem to figure out a way to log out of itunes from my ipod. ie. if I try to download an app, it requires me to put my itunes password in, but it's still logged in as my username. Is this something I should be worried about? Can the new user simply plug it in into his computer and log in with his itunes account? Is there an easy way to delete all personal data from the ipod without deleting all the apps?
