In a bit of a messy alpha/beta game a few days back, foursquare released an alpha version of their app that included BBM integration. Soon after an official update was released that didn't have BBM integration. Well now the app has been updated again and does have BBM integration. So if you weren't one of the lucky ones to get the alpha up and running, you can now grab version 3.1 from BlackBerry app world and get in on the BBM fun. We're not sure if anything else has changed in this update, so if you spot anything be sure to let us know.
