iPhone HD/iPhone 4G running iPhone OS 4 - real or fake?

Add another image to the Taoviet iPhone HD/iPhone 4G prototype gallery, this one purporting to run iPhone OS 4 in all shades of blurred glory.

Did they really get the PRO2 (which is apparently an earlier prototype to the Gizmodo iPhone HD/iPhone 4G unit) to boot up Apple's next generation iPhone OS, or did some enterprising individual launch Photoshop, grab a 3GS resolution screen shot, match all the edges up, and then add the haze? If not, where's the sharp, multi-angled pics and video like yesterday's firmware-only posts?

You tell us -- real, fake, or really fake?
