Ok, so my friend had a jailbroken ipod touch 2nd generation on 3.1.2, and he restored and updated his ipod to 4.1, so he lost all his apps and everything. Does that mean he lost his jailbreak forever? Because I read on the Dev Teams blog that you should not update. Is it possible to downgrade to 4.0 and jailbreak his ipod through jailbreakme.com? Or has he lost his jailbreak permanently?
