Being able to run iOS apps on the Blackberry Playbook means that the tablet could become more popular. A general solution on how to do this is not yet available for the general public but videos proving it can be done were posted on the internet.
The author of the hack goes by the username of businesscat2000. He shared the video proof on the forum Crackberry.com. The posted videos clearly show a Playbook tablet running popular Apple Apps downloaded from the App Store.
Several people on the forum confirmed the video was real and the author of the hack explained how he did it. The hard part was implementing needed APIs so that the apps are routed to use those implementations.
