101 Best Blackberry Apps is a showcase for the best free and paid for Blackberry applications.
foursquare is a cross between a friend-finder, a social city-guide and a game that rewards you for doing interesting things. We aim to build things to not only help you keep up with the places your friends go, but that encourage you to discover new places and challenge you to explore your neighborhood in new ways.
We support all 8000 & 9000 series devices (read: anything with a trackball or touch screen). This version will not work on older Blackberry's (those without a trackball or touch screen)
Whenever a new version of the foursquare app is available, we'll ask you if you want to upgrade. If you choose to upgrade, the latest version will download automatically and your BlackBerry should prompt you to reboot your phone. In the case that your BlackBerry does not ask you to reboot after upgrading, you should do so anyway. It's not good enough to just turn the phone off-and-on -- you must force a reboot by pressing ALT + CAPS + DELETE. This will restart the device without having to pull out the battery.
