While we haven't jumped too far into all the BlackBerry PlayBook apps that are out there (and there are plenty), you can bet come next week they'll be flowing in like crazy. New PlayBook owners will want to fill up their tablets with the best apps from the start, and from the looks of it, FourPlay will be one of the most popular. We did take a look at FourPlay when it first popped up, but being an avid foursquare user I'm super excited to try this app out. FourPlay has been updated and now includes checkins which were sadly lacking when first submitted to BlackBerry App World. The app is shaping up to be the go to for foursquare on the PlayBook, so add it to your list of downloads. It's totally free and will keep you in the loop when you're out and about with your PlayBook. Check out the video above for more.
