I just bought a Motorola HS 850 headset and am having difficulties with some features. I noticed that the only functions that seem to work with the 650 are the call end and answer ( both manual-have to push headset button) and tone on incoming call. Is there any way to upgrade the 650 or the 850 in terms of softwarer to corrrect this to make the 850 more feature friendly. Are there any patches on the horizon. Phone is through verizon.
