Tried updating to 3.0.1 today but got an error message. i assumed i didnt update itunes. before i got a chance to check a message popped up saying to restore to default settings in order to update. i hit ok and tried to do a sync before i restored but it wouldnt allow me to. now the iphone is restored and im afraid that albums i bought from the phone are going to be gone forever. they never got synced into my itunes and i have no idea why or if they're on my backup...im freaking it. its over a hundred dollars in songs and audio books!!! Help?
