Still like Sprint
Still, I prefer Sprint over everything else for unlimited. And I can attest, that I have LTE in a non-launched market on Sprint, SF Bay Area, and the speeds are around 14-16 down. It's the coverage that I can't wait to be expanded.
Than and the iPhone 5 I have craps out sometimes when switching signals, especially from LTE to 3G and to and from Wifi. Sometimes need to cycle data on and off to pick up the best signal when it is there.
