Error Message: iTunes could not back up the iPhone because an error occurred. The thing is - I have no idea what error have I encountered! Usually, I would assume the previous backup file is corrupted and I will proceed to delete the old backups. I did the same this time round, and it's still unable to sync. Now I have no more backup files!I have tried -
1. Deleting old backup files.
2. Restarting iPhone 4S & iMAC.
3. Remove

I've got a 16GB 3GS running iOS 4.0 and all of a sudden today the phone refuses to back up. iTunes is giving me the error "iTunes cannot back up the iphone because an error occurred."
