A while back a new version of Google Maps was released for Blackberry which included mass transit support. That new feature is now available in Google Maps 2.2 for both Symbian S60 and Windows Mobile.

As reported by the Official Google Mobile Blog:

Simply bring up Directions from the main menu and you’ll see a second tab labeled Transit (or Public Transport), where you can request a route using only public transportation. You’ll receive a number of alternatives that take you (car-free) to your destination. Transit directions are available on Google Maps in more than 50 cities.

Other new features include star-ratings for businesses, faster search results, and user-generated content will now surface in your search results.
