Yahoo mobile has actually been around for a few months now, though I think it only applied to certain carriers. I use TMo, and have been using since... Since the fall maybe(?). The local service option is awesome. With a WAP browser you can look up restaurants (for ex, this is what I do alot of), and in a few seconds get the addy and phone #, then hit 'enter' and they're on the phone for you. SO much better than 411.
