Search for local businesses in your area without resorting to your clunky mobile keyboard with the new, quietly unleashed Google Mobile feature found at google.com/m/lcb. When you navigate to the "lcb" page (local businesses?), Google Mobile identifies what city you're in (or tries to—my test had me in either Columbus, OH [wrong] or Los Angeles [right!]), so all you have to do is click through the business categories to narrow down exactly what you're looking for. As the ZDNet post points out, the feature would be a lot more useful if it pinpointed your location within the city à la Google Maps on the iPhone, but either way it could come in really handy if you aren't keen on using your unfriendly mobile keyboard.
