Foursquare is working on a BlackBerry application that should be getting released as a public beta in early December, according to an email conversation between Dennis Crowley (founder of foursquare) and Shane Snow of theNextWeb. For those that don’t know what foursquare is about, here’s a bit from their site:

People use foursquare to “check-in”, which is a way of telling us your whereabouts. When you check-in someplace, we’ll tell your friends where they can find you and recommend places to go & things to do nearby. People check-in at all kind of places – cafes, bars, restaurants, parks, homes, offices.

You’ll find that as your friends use foursquare to check-in, you’ll start learning more about the places they frequent. Not only is it a great way to meet up with nearby friends, but you’ll also start to learn about their favorite spots and the new places they discover.

I’m lucky enough to be part of the testing phase of the foursquare BlackBerry application so I can personally say that if you’re a big-time foursquare user you’ll definitely want to check it out once it goes public.

It it’s something you think you’d be interested in you can get a head start now by creating an account at foursquare.com and “checking in” through their mobile site at m.foursquare.com.
