as far as the proportions go... i wouldn't be so sure. There has also been a rumor that the screen size has decreased ever so slightly. so... if that was the case then it makes that pic seem more valid.
sure. but if it was a prototype of some sort, i doubt they'd be spending all their time polishing it. It's probably getting passed around like a hot-potato. And they had people field testing the iPhone before it came out. This could be the case here. It could just be in the hands of a careless tester. Which would really be ideal so you can see what kind of damages to expect and whatnot. Personally I hate the all black look. But I'm just saying its consistent with all the other rumors I've heard.
It DOES have the tapered edges and such that a few sites were speculating at. The curves are certainly more noticeable and I wouldn't mind seeing a headphone slot shot. And I agree, how would the Frenchies get it first?
