I've been having the worst luck with BT headsets with Caller ID displays with the Touch.
Jabra BT8010, crackling static, just plain useless.
V Three BTH8, disconnects constantly.
You would think I would be talking about the 6800 Mogul here with all my Bluetooth problems, but nope, it's the Touch.
I've had fewer problems with Bluetooth and the Mogul with the 2.17 ROM.
If I can't get a useable BT headset with Caller ID display to work with the Touch, I'm going to go back to the Mogul.
