Sprint may have LTE to all of its sites before ATT matches. If Sprint can deliver as planned, their entire footprint should have LTE by end of next year. Was disappointed in Sprint's KC LTE coverage at first but they keep adding more LTE sites across the metro.
Dubuque, IA which has IBM GDF site still doesn't have LTE from VZ. In the meantime, US Cellular already has there LTE, even at&t already has faux-4g there. Before they got there HSPA+ up and running, I was already getting sometimes 6mb/s download on regular 3G.
