As phones go i think the 7650 was released for people like me and you who cannot wait for the 3650. So with this in mind i dont think Nokia have the intention to release a firmware upgrade that would give us BT Audio. That is my impression from the various posts on this site about the 7650 and BT Audio.
I have only one question i am hoping to get some answers on.
When are Nokia releasing the handsfree w/blurtooth for 7650?
I know nokie BT just support data/fax trafic, but when(or if..) are you releasing BT for speach?
