Hey yeah, I pulled my old Mototola HT820 out of a drawer to try it out with my new Bold, and nearly freaked to see it work in STEREO with Bluetooth. My last phone was Bluetooth 1.0, so I guess I had forgotten the 820 could transmit wireless in stereo. Sounds pretty damn good, too!
(It also has a cord for non-wireless (wired?) stereo operation when you're on a plane.
