Table Connect is an interface that slips onto your jailbroken iPhone and connects a 58" LCD. As you can see in the video, the table requires you to start an app on the iPhone and plug in the cable. Wifi isn't supported at this point.
The two guys in the video seem to access the Springboard just fine, they swipe between pages and launch the Photos app. It doesn't look like a fake, as many readers claimed. The iPhone also seems to be able to output UI elements on that bigger screen just fine
