hey. i have an 8g ipod touch with 1.1.4 jailbreak. today it quit syncing. i plug it in and itunes freezes and gives me the beach-ball. i unplug the ipod and then my ipod shows up for a few seconds on the side bar like it normally would, then it disappears and i get a pop up message saying couldn't read or write to disk. am i going to have to restore?
