I have just bought a new laptop (Asus G51J with the new 720 i7 processor and windows 7) and have a brand new iphone (32GB 3GS) with OS 3.1.2. I have been attempting to set up the iphone, however, iTunes keeps freezing when I attempt to sync the iphone. I have restored factory settings on the iphone and un-installed and re-installed iTunes multiple times and still cannot get it to work. I have searched the internet, and found others complaining of similar problems, but have yet to find a fix for the problem. Does anyone have any ideas? All help very much appreciated.
