iPhone 3gs 3.1.2 jailbroken blackra1n wont sync with iTunes

[phoebe1605]

So i brought a new iPhone in Thailand and was already jailbroken with blackra1n but since it is a new 3gs it is only a tethered jailbreak.

So when I try to sync the iPhone in iTunes it will begin the sync and backup all of the information on the iPhone.... and then stop.

I have checked about 5 times that all the songs and apps are checked but I can't figure out why it wont complete the sync.

Any ideas?
