Although my article for SearchDay yesterday focused on mobile search tools for local info here in the U.S. that doesn't mean that MANY (if not more) tools for local mobile searching outside of the U.S. exist. I plan to cover some of these tools in the future. Danny's post below points out that Google is now offering local search for mobile users in the UK.
Another service that has been offering local search for mobile devices and phones in the UK for some time is Yell.com. They provide info about 2 million businesses, driving and walking directions, and maps. Most of the services are either free or available for a very low fee. Those of you in the UK can learn more by sending a text message to 80248 or by visiting this web page.
