A2DP Adapter for S.E. W800i

[hula]

Hello Everyone,

I have been given a bluetooth stereo headset that I would like to use with my Sony Ericsson w800i to which I paired the headset with no problems. I cannot use the headphones to their full ability though as my phone does not support the A2DP profile and therefore I can only receive/send calls and not listen to my music. Is there such a thing as a plug in A2DP enabled adaptor for the phone that will allow such a thing. Surely I cannot be alone in wanting to be able to join the wireless crowd and utilse the Walkman capabilities of the phone? There seem to be plenty of USB dongles/adaptors for this but not all of us sit by our PC's listening to music we want to well - walk ( cycle even ) with our Walkman phone's!
Thanks for any helpful replies that are returned on this topic.
