I'll follow your lead and add mine, -Enable the characters "S" and "=" on the DUN keyboard so that a Bluetooth connection to the least expensive, always on cell phone service in the USA can be used. (The iDEN handsets, i580, i870, and i880 can use packet data on the Nextel network for $10 a month via BT. My company alone has over 600 lines of service and 150 field personnel that can use the web for supplemental information and services.)
-Add AD2P (Bluetooth advanced audio distribution profile) support so cleaner stereo sound can be streamed to home or auto sound systems.
