A few new changes have happened to BlackBerry App World on the BlackBerry PlayBook. The categories screen has changed to let you first select if you’d like an App or a Game. Perhaps this is setting up to place other new categories in the future (themes?!). App World also seems to have refreshed their app listing, as each channel is starting to fill up. We’re eager to see if these steps are being taken in preparation for App World 3.0, and what else new is to come.
