You must not have an iPhone yourself. Because it's really obvious. But believe what you want. No problemo.
That's the second time you have said that. I'm still not offended.
Those grainy pictures are far from convincing that the iPhone is even an iPhone 3G, much less that it has a super-secret hidden front facing camera. And that's ignoring the lack of logic behind the decision to have three iPhone 3Gs set up a few yards away from Steve Jobs when he didn't even have one to physically show.
I don't know why you're so married to this idea, but someone who literally can't accept differing opinions isn't worth talking to. So have fun.
