This comment from John Gruber:
I’d love to hear the backstory on how 9to5Mac got these images. 9to5Mac offers no explanation for how they obtained them. Product marketing images and the names of new iPhones almost never leak from Apple. iPhone names sometimes get leaked in iOS builds, but not photos like these. These photos were almost certainly intended for the keynote. To my memory, this is unprecedented. My guess is that no one at Apple gave these images to 9to5Mac. I suspect Rambo, who is extraordinarily clever at finding things, somehow discovered them through a URL that was exposed publicly but should not have been.
This sounds feasible to me. I’d guess that some folks at Apple are having a very bad day.
