Okay, jailbroke my iPod 2G iOS 4.2.1 2 days ago. I had a set theme that I liked and used it. But later, I changed it back to one of the default iPod wallpapers (the Earth one) and now I cant change it back. I know I can pic it and send it to email, and into camera roll, but the one I really want is animated. I checked in /var but there is only a LockBackgroundThumbnail.jpg, and not the LockBackground itself. Deleting the thumbnail has no use. Any ideas, please help!!!
