Cingular rolling out new detailed coverage maps in Spring of 2006. A Cingular / AT&T official called me today explained their new maps that will be rolling out into stores and on their web site near the end of April.
Here is a summary of my conversation: "Cingular's new maps will be similar to T-Mobile but a little more simplified. These maps will provide 4 colors indicating coverage. Good, Better, Best, No Coverage. The maps will provide detail down to the street level. In areas where they have deployed 3G these areas will be indicated in dark blue. 3G has been deployed in 16 cities and should be close to 80 cities by the end of 2006."
