Google just unveiled its latest service for cellphones.
If your phone has a Web browser (that works with XHTML — about 70 percent of current phones do), direct it to mobile.google.com/local. (Bookmark it so you won't have to type all that the next time.)
In the What box, type in what you're looking for, like "Italian restaurant." In the Where box, put your Zip code (or city and state). Click search, and boom — Google shows you the Yellow Pages and Web results, in a list and even on a map (which you can scroll or zoom).
By highlighting a result, you can click to place a phone call to that place, or get driving directions from your current location.
It's all free, and there are no ads. You go, Google.
