Understanding that none of them show all the tiny white dots that exist in the real world (dead "spots" that can be larger than a city block), you got the colors right.
Sprint's detailed map on their site - you can get it large enough to have more than one pixel for a small front lawn - shows solid 2G coverage at my niece's house. I dared them to come out and prove it with ANY equipment but they declined with the usual "the maps are approximate" nonsense. There's absolutely no measurable signal in her house except for one very weak reflection off something deep in the woods behind her house, because she's under the knife effect of a ridge - and that reflection goes from whatever is causing it, through an upstairs bedroom window and out the roof. You have to stand with the phone pressed against one spot on the window, about 6 feet off the floor, to get one bar. But the map shows solid coverage. And I can't find the "connect the phone to the map" app.
