I broke down and called t-mobile. I explained the situation, and they said to do data only on a "device" like what I described, the T-Mobile Total Internet plan was the way to go. No annual contracts, just straight up internet unlimited, and voice calls if you wanted. 39.99 per month, so around $50 with fees and taxes depending on state. That's higher than I want to pay per month just for the novelty, plus I get way better coverage with Verizon and tethering my EVDO rev.A BB up to it. I just hope they get the BlueZ team gets the DUN protocol up and running for the N900 for us weird tether a phone to a phone kind of folks. What can I say, Verizon's service and more importantly coverage are too vast to compete with. Food for thought anyways.
