GoogleのLocation Search
google.com from your Windows Mobile phone's browser and performed a local search, the results were tailored to the last location you entered. Now, using the Gears Geolocation API, Search with My Location approximates your actual location using the same Cell ID technology used by Google Maps Mobile. So if you want to find sushi nearby, just type "sushi" and Google will return local business listings around you. If you want to know the forecast, type "weather". If you want to search somewhere else, specify a location in the query like "pizza Kansas City".
Winodws Mobileの一部のスマートフォンでは基地局情報をもとに近場の施設や店舗の検索ができるGoogleのサービスが海外で始まったようですね！
日本でもこういうサービスは早いところやってほしいですね〜？
