Foursquare for BlackBerry has been updated to v3.3 and is available for download from the BlackBerry App World. There is a new icon which has been updated but other than that there are just a few UI improvements and no new feature has been added, like the new ‘Radar’ feature for iOS 5. The usability of options is smoother and there’s an addition of notifications (over the logo) with this update. You can download the latest update over here.
