This may help. Here are Verizon's 3 maps. As you can clearly see, it's their 3G map, but colored like their 1xRTT map, I'm sure since their brand color is red and AT&T's is blue.
It's hard to tell in some of the continental US areas, but Alaska is a very easy to see example. They didn't even include their "Extended Enhanced Services" in the 3G map in their commercial, even though they do on their website.--
