AT&T filed the suit in U.S. District Court for the Northern District of Georgia Tuesday accusing Verizon of false advertising and deceptive trade practices.

The Verizon commercials are in response to AT&T's "There's an App for That" ads touting the thousands of applications that can be used on its smart phones.

Verizon's ads show United States maps with areas highlighted to depict its available "3G" coverage - which allows users to access data faster.

In comparison, it displays a map with AT&T's "3G" coverage with blank spaces to show where the service is not available.

AT&T says those maps are misleading because there is still coverage in areas where "3G" service is not offered.
