Anyone have any luck with pairing a new AT&T Tilt (Windows Mobile 6.0, aka. HTC TyTN II/Kaiser) with a 720? They "saw" each other and it says it can do hands-free calling (haven't tried yet), but so far it won't play ball on the data side (so no traffic, weather, etc.). Ideas? Tomtom support is, so far, unaware of the phone or the problem.
