RESEARCH TRIANGLE PARK, N.C. – A “my network is better than yours” fight between Verizon Wireless and AT&T is getting nastier by the day. Can you hear the news?

leveled the latest blast Monday in a biting response to claim that reliability, not speed, is more important in the wireless world. AT&T is fighting Verizon’s advertising campaign that it offers “America’s most reliable 3G network” with a complaint field at the Council for Better Business Bureaus’ National Advertising Division.

“Verizon’s claim that speed is not a relevant factor to a reliable 3G network is preposterous, especially when in response to the question ‘Why do you need 3G?’,” AT&T said in a statement attributed to Michael Cole, a spokesman in Dallas.

“Verizon says on its website: ‘In today’s fast-paced world, there is nothing more frustrating than having your day held up by slow-moving downloads.’ We couldn’t agree more. Data network speed is an essential factor to consumers when it comes to data transmission on their wireless devices. The 3G reliability claims made in ads by Verizon Wireless are false and misleading.”

Verizon is asking a federal court to back its “most reliable” claims. However, AT&T issued its statement after reading a Bloomberg news report about the dispute.

In its federal court complaint, Verizon said the following, according to Bloomberg:

"AT&T has invented a new formula for calculating ‘reliability’ and claims that by applying this newly concocted formula its 3G wireless network has superior reliability.

"AT&T’s claim that speed is an essential component of 3G network reliability and that its formula is the proper standard for measuring 3G network reliability is without any support whatsoever."

The court and the ad bureau folks may ultimately decide who has the right to say what about their network. But the real bottom line is this:

What’s the consuming public, which pays the bills, consider the most important factors in wireless?

What do you think?

Of course, other providers (Sprint, T-Mobile, others) offer their own networks and claims. Isn’t competition great?
