Tweetolio, currently one of only two Twitter apps for the BlackBerry PlayBook, has been updated to v1.2.17. The new update has fixed the sticking in scrolling through tweets, and has also corrected the keyboard pop-up when clicking on text input areas. The app is still lacking some other normal functions you might find in a 3rd party Twitter app, but it is by far the best Twitter app for the PlayBook (that was available through App World). It seems the app has been pulled by the developer, but if you have it still installed the update should get pushed to your device.
