From everything i have read... no.
I managed to get my moto ht820 to work, but mono only... which rather sucks. I am now using it with the audio cable that it came with and an adapter, but the audio still is coming out of the phone. (it does not do this when I use the headset via bluetooth, but again... it is in mono and sounds pretty crappy)
I have been looking around trying to figure out if the upgrade to WM5 might fix the issue... but this is my only phone at the moment, so I have not been too free to do too much testing.
if I find anything else out I will repost.
