Google has updated its mobile app for Windows Mobile. The update includes My Location, Google Suggest and Search with Maps.
My Location gives local results for searches. Now, if you're searching for local pizza, simply type in pizza instead of a longer query like "pizza + city + state."
Google Suggest is Google's query suggestion feature.
Search with Maps, like My Location, enables local search. You'll need to have Google Maps installed on your phone. Then enter a local search and little red pins will show you relevant search results.
