Let us know your iPhone signal with the new Google Maps mashup site called SignalMap.

SignalMap works by asking users to post their carrier’s cell phone signal and mobile phone model by your zip code. If you know of a deadspot in your carrier’s network be sure to add it, as most carriers show great coverage on their network maps. If you want to see how it works type in 27604 and select Sprint network.
