I'm on my second 6315. I have a new Jabra BT200 also.

50% of the time the headset wont picket unless I reset the iPAQ.

If I leave bluetooth enabled, my iPAQ will lockup within a few hours. Turn off Bluetooth and its fine. (Note: my first 6315 would lock up regularly regardless of BT or WiFi!!!).

So....not very usable if you ask me.

Oh, and the range for the BT200 is pretty crap.
