When I had a Verizon wwan card in my company laptop I set up ICS and had an ad hoc wifi connection to my 770. I think windows limits ad hoc wifi to 802.11b speeds. But it works. Couldn't try bluetooth because my IBM thinkpad had no bluetooth.
Worked great as my IBM was a battery powered mobile hotspot...yes I could have surfed directly on the IBM but that wouldn't have been as cool now would it?
