People often tell me that all they want their cellphone to do is to make phone calls.

But what about saving money?

Verizon Wireless said today that certain customers can download an application that can help them find the cheapest gas. With rising gas prices, Verizon Wireless obviously wanted to talk about it now; the service has been available since October.

The application, called MobileGates' FuelFinder, is available to Verizon Wireless customers who have "Mobile Web 2.0" service.

It lets you search for the best deal by Zip code, city or recent search, and it retrieves information on more than 110,000 stations in the country. The data is updated every two hours.

The small print: FuelFinder is available on Mobile Web 2.0-capable phones for $1.99 a month. Mobile Web 2.0 is available for $5 a month.
