I am in a unique situation. I am using a GSM phone with GPS mainly as a location sensor. So, I don't need any voice minutes, just unlimited data, for as low a cost as possible. 3G would be nice, but don't even really need 3G. Other than spotty coverage, Boost fits the bill perfectly. They have unlimited data for 0.35c per day.
