Nokia has released Universal Search, a feature in beta aimed at making it easy to find both applications and phone features easier. The feature is available for download for symbian 3 phones, though on beta(remember to give feedback after use for better development). This gives the ability to have an instant search while you type and the results show below the search with firstly search results from within the phone and then results from the web. You are also able to map locations in search results.
Download and test the app if you are on Symbian 3 here, doesnt guarantee you miracles though.
