Lemma for the BlackBerry PlayBook has received a small updated to v1.1.9. This update has no change log available at this time but I would almost bet that it is just a couple of bug fixes. Looking for a Twitter experience that makes full use of your BlackBerry® PlayBook™ 7-inch screen? Are you the follower of hundreds of Twitter users, making your use of Twitter lists mandatory? If you answered yes to either of these questions, Lemma for BlackBerry® PlayBook™ is a Twitter application you’ll want to check out.
