that might be 'shopped' ...
the image at the bottom of the article looks realistic though. Hard to tell these days.
it was the iphone safari useragent that was detected in the wild before the release. here is a link, dunno if it was the first sighting though...
What I would really be interested in seeing are the log leaks that directly revealed the first versions of the iPhone.

Or maybe this was for the unibody Macbooks, I forget.
