I can't get it to work. I tried two headsets and it pairs OK and I select Wireless Stereo in the checkbox. But I can't get any audio to transfer over the headset, WMP just plays out of the built in speaker. I various combos of headset buttons, but it will not connect. Widcomm had a nice feature where you just tapped and held the stylus over the device and a popup gave you a "connect" option. No such convenience with the MS BT stack on my Sprint 6700.
