I guess it's in the middle of page scrolling. Regardless, probably a fake photo anyway.
Edit: Ops, just noticed it. You're right, picture is misplaced within the frame.
It's not misplaced. It looks more like something's in front of the screen.
To all the people claiming it's a fake...really? The fact it's so crappy is what makes me think it might be real. If I wanted to pretend I had the latest version of iOS, I'd jailbreak my iPhone, install a new theme, and take a much better shot than what we're seeing here.
This looks like something someone took in a hurry, which leads me to believe there might be something to it.
...though really, even if it is real, it's not the most revealing or informative thing that's ever been posted here. All we can tell is that the icons are slightly different than what we've got in iOS6 and not much else.
