Google Maps for Mobile has received an update for Blackberry and Java-capable handsets, adding in bus/train directions for the SF Bay, Seattle, New York, and over 40 other cities. Quickly find the closest bus stop, the route to take, and whether or not you have time for one more drink before the last stop of the day.

I can not even imagine how much time this will save me. I lived in the SF Bay for 18 years, and I still stare at transit maps in horror. They look like normal maps after a unicorn crapped a rainbow on top. I have no shame in admitting that I have gotten on the wrong bus more than once, as I’m completely convinced that transit maps are designed as the next step for people who have already mastered Sudoku and Rubik’s Cubes.

The download is available now. If your handset can run Google Maps for Mobile, just head over to http://www.google.com/gmm to grab this release.
