Foursquare has an Alpha version of 3.0, and it works with BBM. The UI is nice and crisp as well. One must keep in mind that this is an Alpha version, which means use at your own risk. I had some trouble with the BBM integration to work, I’ll tell you how I did it…
When I first downloaded the Alpha, the BBM integration failed. I simply redownloaded the Foursquare Alpha app, then after the reboot, it had four steps to integrate BBM. This is on my BlackBerry Bold 9650 with OS 6. It went through four steps of verification, then rebooted. When it rebooted, it asked for me to sign into my BlackBerry ID and it worked. Now when I check in I have the option to include BBM and it does post to my BBM.
I love the way the icon and UI look. It’s smooth and works great.
If you’re adventurous and want to try the new Foursquare Alpha, you can grab it for free.
