I got an XPS 1500 and had horrible problems upgrading from XP on a different machine. Dell spent >100 hrs figuring out how to get it to work and ended up using a directory named TEST as the home for my user account, instead of the user name. Now I can't get iPhone to sync. It never even completes its backup phase. I tried changing the user name for TEST and recreating my account in the correct directory, and then copying the data over, but no love. Any ideas? TIA
