It appears that T-Mobile has realized that it's better to educate customers than to try and pull the wool over their eyes. Recently available is Personal Coverage Check that provides realistic (even pessimistic) coverage information to the street level.

Those of you who know my address or are familiar with Old Dominion and 193 headed in toward Washington, DC will not find any surprises here. Particularly nice is that we now know where their towers are. Of course, I'm sure the DHS will be lobbying to take that info down pronto in the interests of "National Security."
