Many BlackBerry users are familiar with the ALT+RST method for resetting the local cache of App World in your BlackBerry smartphone. David pointed out to me that this method also works on the BlackBerry PlayBook without the ALT key. You simply bring up the keyboard by swiping from the bottom left bezel and type in the letters “rst”. I have not managed to confirm with anybody at RIM exactly what this clears out and have not had a chance to do any extensive testing but let us know what you find!
In case you were wondering exactly what this does I would recommend reading my previous article about how App World is designed to be slow. In short RIM caches content on your device for up to 7 days. This should clear that out… hopefully. Let us know how it works for you!
