Hello, currently i have an Ipod Touch 2g jailbroken on 2.2.1 and am looking to upgrade to 3.12. After I upgrade i have to re-jailbreak, correct? Also, recently my hard drive crashed and I had to get a new one, so basically I have none of the music/vid files on my computer that is on my Ipod so it say i have to erase and sync with the new itunes library. Does this mean I will lose all my music if I sync? Thanks in advance. EDIT: I won't let me transfer purchases to my computer from my Ipod because i've allready authorized 5 computers. I can't deauthorize any computers because the librarys that are authorized don't exist anymore.
