We covered the Table Connect for iPhone (a 58-inch surface that mirrors your iPhone screen) a few days ago, and now the developers posted a video of the "device" in action: as you can see in the video above, the table requires you to start an app on the iPhone (likely available through jailbreak) and plug in the cable. Wifi is not 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.
The Table Connect is still in development, so we'll keep you up to date with the project.
Update: some readers have pointed out that the guy in the video holds the power button down when firing up the app required to output the iPhone screen.
