I HATE APPLE!!!!! EVERYTIME I have updated the OS, I have lost evrything on my unit. I synced and backedup but after downloading the new software and telling it to restore from a previous backup, it STILL is empty. NO MUSIC, NO APPS, NO PICTURES.... NOTHING!!!! I realize I can re-download the apps without having to pay again. However, what do I do about my purchased music? What am I doing wrong?
