I don't know about everywhere, but I do know that vzw has been setting up 4g antennas in tons of areas, actually having them setup, especially in smaller markets, like the ones in east Texas, and similar areas. They've been doing this since August of last year, possibly before that. In many, many areas the systems have been operational, but turned off. The blips of functional 4g that people have been reporting are of course towers that were brought online for testing and calibration. Its been a very extensive and pretty hush hush thing. They made deal after deal to get this to happen. But it was very lucrative for those who were willing to get on board.
Some of the time they were a PITA to deal with too.
