Hey guys, like many others have said, this is just a bad photoshop job. It's just an iPhone 4 picture taken from the front but made to look like the picture was taken from an angle.
One of the last places to look for leaks is their website. (Granted, they leaked the Thunderbolt displays in advance this year, but that was a surprising exception). The thing is that Apple is strictly divided and remains specialized. My cousin, who works in the iPad department, has no idea what the next iPad will look like or when it will come out... even though he works in the iPad apps department at Apple! Of course he could be fooling me, but I've known him since childhood, and he can't play poker if his life depended on it.
So I have no doubt in mind that the website people at Apple have just as much of an idea about the iPhone 5 as we do. They'll likely be notified maybe a week or so before its release to make sure the pictures and descriptions are up and running after the Sept event.
