I did a jb a couple months ago, I loved it but then it froze on me causing me to restore. So I decided not to jb again. So now instead of having the original "AT&T" on the status bar, it has my name. Do I need to jb it again to change it back? I also remember when I did a back up after a restore, it went from AT&T to my name. I have a 3gs, 3.1.3 and I do remember saving some sort of file to someone(in order to jb again i suppose?) Any ideas? Thanks!
