We just launched a new tool to Compare Wireless Coverage from T-Mobile, AT&T, Verizon, Sprint & US Cellular. We are hopeful that AT&T, Verizon & Sprint can provide us with a similar iframe map to make it easy for consumers to compare local coverage. The great thing about the map provided by T-Mobile is that you don't have to leave the page to zoom into a particular location.Stay tuned to see if we can get a similar map from AT&T & Verizon.
