I have to send my ipod into apple so they can fix my home button. when i right clicked on my ipod in itunes and selected "Back Up", it made the back up but when i go into preferences and click on the "Devices" tab it only shows a back up that i make in August! i think i was using like 1.1.4 back then. i mean, i have synced tons of times and it would make back ups before the sync but none of them show up! i have jail broken.
