While not incredibly well filled out yet – you can get the idea. Here’s what I can tell you about Cingular/AT&T in the Denver area… You’re screwed unless you live Downtown. Well, ok to be fair you’re pretty much screwed by every carrier (except Sprint) in the Denver area. At least according to the maps.

It’s only a matter of time before a secret email goes out from some mis-guided management type to have the staff of said carriers go and pad the stats … so add your own now. For once let’s get some realism in those coverage maps!!!

We’ve all taken a close look at the multi-colored cell phone coverage maps when we’re considering cell phone providers, but unfortunately nearly as many of us have found out that the coverage maps don’t always tell the whole truth. Google Maps mashup SignalMap tracks user-submitted cell signals based on carriers and locations, giving you a better insight into real world signal expectations for coverage.
