OP thread jack, but follows where it went..
It may seem like most of the major cell phone providers at least may be considering LTE. But by the looks of things, Sprint is thinking a bit further, and with the partners mentioned, it's not in bad company.
As I see it the carrier's are looking at a way to increase bandwidth for thier cell phone customers, but Sprint is looking at a larger picture and thinking Wireless Broadband for all everywhere.. IMHO
