Hello maybe someone on crackberry can explain what the dark spot beside the front camera and above the speakerphone, on the white version of the iphone you can see a little dark spot. Just Curios light senor or something?
It's in the same place on the black iPhone, you just can't see it because it blends in.
In any case, the black dot to the left is a front-facing camera and the one above the speaker is a proximity sensor - the thing that signals the screen to turn off when you get close so you won't face dial.
