I figured this has been covered before, but with all my experience using WM devices, I haven't figured a work-around.

I use My Mobiler to relay KVM functions from the phone to my desktop. I can then easily navigate my Treo and compose text messages through my PC's keyboard.

I've noticed that when the Treo is connected to my PC via USB, and with an ActiveSync connection present, the device disconnects from the cellular network and possibly routes IP traffic through the PC. SMS relays work, but I can't check E-mail or browse with PIE while tethered to an ActiveSync connection.

Is there a way this can be changed so the Treo maintains the cellular/EVDO data connection while connected to my PC, without tethering my PC off the cellular network at the same time?
