Google Maps is improving day by day (or at least until the next update), with the latest version throwing in mass transit directions on its S60 and Windows Mobile versions. Version 2.2 can easily be downloaded and installed on your smartphone’s browser, just make sure you’re on a decent data plan as it can end up to be pretty pricey if you’re paying by the kilobyte. This latest update will see 50 cities all over the world benefit from transit directions, and it goes without saying newer cities will be added in future revisions.
