I got a new 8310 a week ago and am still not able to get the BT headset working. I have tried two different ones (Plantronic 340 and 655).
Both the headsets work perfectly on my older Pearl but not on the Curve :(
On the Curce i am able to pair the headset, but as soon as i try to make a call it terminates the BT connection and the headset can't be used. The connection get re-established when the phone call is ended!!
