There's no real killer app yet for retrieving listings information on your mobile phone, but there could be soon.

On Aptil 11, FreeMobile411 launches the consumer version of its carrier-offered services. Visting FreeMobile411.com from your mobile browser gets you a decent-looking ad-supported WAP site that simplifies directory search and helps you avoid long waits while listening to ads from dial-in services like 1-800-FREE-411.

Enter the search term--it can be a business name ("Blockbuster"), business type ("video store"), or person ("Bill Blockbuster"). Then select the search type, and fill in either the city or zip to search or browse listings. From there you'll have a spectrum of choices to plot on a map, get directions to, dial with a click, or use as an anchor while searching for nearby gap pumps, hotels, banks, and so on. You'll still be able to connect to the operator at the usual carrier rate, but with this useful, easily navigable app, it's doubtful you'll ever need to. P.S. It even looks decent on the RAZR!
