i keep running into the same problem, whenever i try to sync a bluetooth stereo headset, handsfree connects just fine. but then stereo audio always fails w/ the connection. i've tried 2 different sony headsets, and now my brothers jabra dogtag. All of which work fine with my tilt (ttyn ii) and fuze (touch pro). If ANYONE can find a way to get the MS stack into this, and it fixes the problem....consider paypal funds on the way.
