Microsoft's Tellme division has come out with a voice-activated search service for the BlackBerry. After downloading the application, users merely have to push the handset's "talk" button and speak their search command to find a business, movie theater schedule, traffic info, driving directions and the like, the AP reports.

The service, which only works with newer BlackBerry models, uses GPS to determine the user's location and returns results gathered by Microsoft Live Search.

It also competes with the new voice search component of Yahoo's oneSearch, which will mean competing with itself if Microsoft ever gets its wish granted, you know, the one that has Yahoo's board saying "Sure, take us over. No problem."
