No, the basic idea of some simple fake was:
1) Take a screenshot of PS on a PC
2) Tansfer the screenshot from the PC to the iPhone
3) Display the screenshot in an Image Viewer on the iPhone
4) Take a photo of the image in the viewer
Anyway - PlaneShift is not executed on the iPhone, just displayed. Still, it is impressive, you are using the iPhone as a kind of "remote control incl. monitor" for your PC then. Nice idea. A really "more advanced fake".
