These photographs are super-grainy and badly lit on purpose, hiding the mistakes always associated with fakes. BUT... the supposed official Apple promotional material is open in what seems to be Photoshop -- at any rate, it's a digital file open on a computer. If it was real, only the biggest of morons would PHOTOGRAPH the computer screen. Every other person in the known computer world would do a screen shot (or screen print if you're on a PC) so that the file could be seen in all it's Apple digital glory. -- that or more simply: You size down the image in PS to something web-managable (say 800 x 600) and just post that around the web.
One can look at all the glaring errors in the images that make up the document to prove it is unofficial, but this, to me, is the biggest smoking gun we've got. You don't photograph the bloody monitor! If this were the phone itself, obviously you photograph the device from many angles (not just one single doofy photo of it sitting in a box (recent retarded fake)... but ask yourself: WHO would have this digital file anyway right now? I would imagine Apple does all its own printing for privacy's sake. If not (and I'd be highly surprised otherwise), the printers would be under strict contract to not allow any images out in the wild.
If anyone had anything real at this point (not associated with Apple), they would have the printed poster, which (if real) would be photographed many times -- from whole poster to close-ups of all the elements to prove its authenticity. This is could've been a more convincing fake if the faker-at-large would've have created this at poster resolution (20"x15" @ 300dpi, let's say) and then had it printed. Then taken photographs of the poster.
Of course, FAKER doesn't want the Mac Community to be able to see the lame quality images he has or the crappy low rez icons he's found for iChat/Exchange or for the crappy copy he's written to be scrutinized by those much more creative then he is. So he takes a photograph of his poorly-lit monitor and hopes it passes mustard.
It doesn't, fool.
