I have what sounds like a related challenge but I don't believe it's a problem, just the way it is.

I leave my TP plugged into my desktop PC at work while i'm at my desk. When it's connected, it uses my work internet which has restrictions and I also have discovered that my problems with picture mail are from this as well. While i'm connected to the desktop PC and using my work's internet I cannot send or receive pic messages and even after disconnecting they never arrive on my phone.

I don't know if this observation helps but I think the solution i'm looking for would fix yours too:

I want to be able to be connected to ActiveSync via USB but use my phone's (Sprint) internet to browse etc. I think if there's a way to force that connection it may solve your problem as well.
