I believe Verizon disables DUN because they don't want folks to be able to use multiple clients through one access point paying for service for one device.

I signed up with Sprint EVDO service with a Samsung 920 because Sprint does support Bluetooth pairing and DUN, for 39.99 for unlimited.

The only downside is the service will disconnect after a couple minutes if there's no activity. I've had to learn to launch some low bandwidth streaming to prevent disconnections.

I use the service with my 770 and for my MacBook.

When I was on the train from Eugene, OR to Portland a couple weeks ago, there was a guy behind me who was struggling to find WiFi hotspots as we were rolling. He was rambing on his phone about it. I got up, gave him my account name, P/W and phone number. He added that to a Bluetooth profile and connected through my phone. He had internet all the way to Portland.
