Foursquare for BlackBerry has been updated to version 1.5.  There still isn’t any love for BlackBerry Storm users, however, you can get 1.5 to work (sort of) if you disable compatibility mode.  If you aren’t on a Storm, or Storm2, version 1.5 adds the ability to add friends and tips.

You can download Foursquare for BlackBerry by visiting http://foursquare.com/blackberry/beta from your devices BlackBerry Browser.
