Force Activesync Connection

[Hind1]

Hey all,
My brother dropped his Diamond, and the screen is no longer displaying anything or responding at all to touches. The phone still starts up and is usable through hard buttons, but other than that can't do anything. Before re-flashing stock and re-locking the phone he wants me to save his contacts, which I know I can do by copying the pim.vol on the device. The only problem is that usually when he plugs his phone in to the computer, he uses the removable disk option rather than the Activesync connection. This means that I only have access to his internal storage, and I can't for the life of me figure out how to get the phone into Activesync mode. Is there any way to force it?
Thanks in advance,
