I have Sprint, and the new Palm Pre, I have to say I love Sprint, the coverage has been great, and I get voice and data pretty much everywhere I have been. On a recent trip to Vegas I may have lost coverage twice at most and those where in BFE. My last experience was with T-mobile and I did not get reception at my house or work, both were in areas that were supposed to have the best coverage areas. I really cant explain how well sprint has been for me, plus if you are a costco member you can get upto 23% off your bill, also if you get an unlimited data plan i think you get unlimited mobile to mobile calling which is just awesome and blows the competition away.
