Honestly, with how low the 4G WiMax is going right now, I'm not sure.
They better get moving soon, though, otherwise Boost and VM will have a LOT of unsatisfied people on their hands
I live in an area where WiMax isn't right now. It doesn't really bother me, though, because I have WiFi. So does work, and starbucks, and McDonalds, and almost everywhere else in the world these days.
However, when sprint ends its 3G, I better have a good amount of 4G coverage (By then I'll have a new phone, as well. Hopefully sprint makes an Evo 3D LTE and VM gets it. I would be incredibly happy.)
