When syncing iphone 5, itunes hangs on backup stage I have a new iPhone 5 (iOS 6.0.1) and successfully configured it with a backup of my old iPhone via iTunes on my Windows 7 PC. This basically transferred all my settings, media and apps.

I added some more music to my iTunes the next day and tried to sync my iPhone. So I plug in using the Lightning cable and click "Sync". I goes through the motions until it hits stage 2, backing up. Here it hangs and never gets past this stage. I left it on overnight the other day and it was in exactly the same state in the morning as I left it the night before.

I also can't seem to skip the backup stage by clicking the x. it just seems to freeze up for a bit when I do and then resumes the never ending backup.

Any advice on how to solve this as I literally just want to put 1 album on my iPhone and at the moment, this isn't possible.
Delete any old backup related to this device


Open finder
command-shift-g to open the go to folder.  Put in ~/Library  Hit go
Navigate to Application Support > MobileSync > Backup
Order by Date Modified and look for the latest folder which should be timed at the last time you did a backup.  Drag the folder out to the desktop
Try to resync with the phone


If it all works you'll get a new backup in the folder, delete the one on your desktop.
