The company behind the popular ExitStrategy app, JWeg Ventures, let me know that they have released some awesome new apps for NYC BlackBerry users. They released the NYC Subway map along with apps for the bus routes in each of the 5 Boroughs of New York City under the JustTheMap name. They also have maps for Barcelona and Washington Metro. The maps look awesome and I cannot wait to play with them. They are releasing the apps under the JustTheMap name.
You can find the NYC Subway Map for $2.99 at this link in the App World. They also have the bus maps for $2.99 each and you can find the Washington and Barcelona maps at the same link. The application essentially downloads the maps to your memory card so it does not eat up your memory but that takes some time. Personally I wish they just created one app that let you download other maps. They should also add in some GPS and cell tower triangulation if they can!
The maps are officially licensed MTA maps so they look exactly like the official map!
