Many of the commenters at the Engadget site thought the photos were fakes. The rest didn't like the color white which they thought was gay. Those photos probably are fakes and it really doesn't matter.

What really matters is how well the 3G iPhone will work for users when it's introduced. I wouldn't be spending time staring at the back of my iPhone, anyway. I'm buying it to use with the screen up to my face. If it has a good grip and is comfortable to hold onto, (along with excellent internal hardware and software) then I'm buying. Secondly, I'd keep it in a silicone skin, so I'd rarely ever see anything on the case except the screen. Only a bunch of supreme nerds are going to sit around and speculate about some unsubstantiated photos and start bitching about the color.

This reply is not a knock on you showing the photos, so don't take offense.
