Pacemaker did an awesome job with their music DJ app for the BlackBerry PlayBook. Both the lite and full version of the app were updated this week to v1.1.1 and address one of the main weaknesses in the app. According to the official @pacemaker Twitter account it adds stability updates along with the removal of a nasty bug that was left from the beta version. You should update because if you don’t that beta bug will disable the app on July 1st.
Also worth noting is the fact that Pacemaker has answered about the differences between the full and lite version and clarified that there is no way to upgrade between the two.
