i have been recently having problems on my jailbroken ipod touch 2g. i was trying finding out what happened to my save data on my ipod touch. but to fix this i just right clicked on my ipod in itunes and chose "restore backup" i chose the one that had the date and time of when it was backed up. Maybe i'm just a noob. but i think this could help some people who have spent hours playing games, and then losing their save data.
