Those rocking with Slacker on a BlackBerry PlayBook may want to fire up the App World and download the latest update. Yup, the Slacker Radio app for the PlayBook has been updated. This update brings the app up to version 1.2.6. Otherwise, while we can see that the update is ready and available — the BlackBerry App World listing was not quite as forthcoming in terms of what has been updated. Simply put, there is not any change log given, however we are hoping that it fixes the skipping issues that began when the PlayBook was updated to OS 2.0.
