Have had my XV6900 for about a month now and have not been able to get the phone to sync over the USB cable. It initially seemed to work, but then stopped syncing after about 5 minutes, and then in many cases my computer won't recognize the phone at all.

I don't know if it matters, but I have 4,500 contacts in Outlook. My prior Samsung i730 had no problems syncing. I'm able to sync using wireless sync, but I cannot install any software using wireless sync or transfer songs onto my microSD card..

I tried calling customer service and they had me reinstall things and that did not help, and then I got cut off and didn't have time to try again.

Anyone else have this issue and figure out a fix?

Thanks for any help.
