This is what I get when I try to back up, with iTunes, my iPod Touch 2g running 2.2.1 firmware untethered & jailbroken: Please Register or Log in to view images My iPod used to back up all the time no problems until I installed aptbackup to see what it was like (bad idea) and then it gave me this error. I can still sync music, video, apps, etc. but it just won't backup. I tried uninstalling aptbackup from Cydia and that didn't solve it. I tried restarting my computer and my iPod after uninstalling aptbackup but that didn't affect it at all. Can anyone think of any more solutions to this? Does aptbackup mess with my backup files? I assume it must in order to back up the list of Cydia apps.
