Getting ready for the new iPhone? Here's a tool that will help. The Open Signal Maps site compares coverage in various cities across the US, UK, Italy, Germany and Spain.

Select a country, enter your address or zipcode (do not be put off by the limited "city" pull-down list) and check the signal stats in your location. In Denver, Verizon had the highest scores. The interactive map allowed me to switch back and forth between Verizon and AT&T to spot-check particular places.

How does your location rate? Is the map showing you a carrier you hadn't considered? Drop a comment and let us know whether this information changes your mind.
