Hey guys, i currently have an itouch running on 3.0 firmware. well, it used to be 2.2.1, and now i want to go back. can anyone tell me how to do this because when i try to restore it to 2.2.1 it just sais "can not restore ipod "ipod" because an unexpected error occured. Error 20" how do i fix this? this error is one i get from trying to downgrade to any other firmware on my itouch, so what, is there some special other way to do it or sometjin?
