I've got a problem and need a solution, when driving in car I MUST wear a headset, I have been using the headset that came with the pre, but I AM VERY ANNOYED by the "sidetone" and I just can't take it anymore, it dosent help that my car has a VERY loud exhaust BUT I never had this problem with treo 800w using wired headset. Now my question, do bluetooth headsets also have this annoying feature (I know some of youike sidetone) but its driving me insane and I just cannot drive and hold phone at same time it kills my elbows. Please any suggestions on a headset wired or bluetooth with NO SIDETONE.

Thanks a million in advance
