| | I was right there with you over the weekend, Matty
Here was my solution:
The Tmobile rep walked me through how to do a log of my intellisync. i went into the log file and found the contact that intellisync was quitting on. They were surprised to find out that it wasn't a $ # or unusual character - there was nothing unusual about the contact at all. When I deleted it and retyped the same info into a new contact, it synced fine.
