Struggling to find a way to send/receive an MMS message while connected to my desktop via usb cable and ActiveSync running.

The "big picture" goal is to have MS Remote Control Display running so I can see my Treo 700w on my desktop screen and be able to send and receive an MMS message.

It appears the "Broadband Access (#777) can't go out when tethered. Struggling to comprehend...

Thanks in advance.
