So my wife picked up a white 4s today and tonight while installing some apps for her, I ran a flashlight app that I have on both phones. Interestingly on her white I phone you can very clearly see the LED Shining through the white case around the area that is actually visible whereas on my black iPhone, the case obscures that bleed-through and thus in a dark room the output on her phone is greater. I would imagine the same would be true for the camera, I just haven't tested it yet to see if that's good or if it will interfere with the images in any way.
Stay tuned.
