Hello,

I think he is talking about the sensors above the speaker that detects when the phone is up to the side of your head when you are talking to cut off screen and so you will not hit a button during a conversation.

Hmm... that would make sense. (feels like a retard)

The small round circle is present on the ipod Touch as well, it is a light sensor used by the auto brightness feature of the screen to detect ambient light and adjust the screen brightness accordingly (so if you are in bright sunlight the screen brightness is reduced to save battery, if you are in the dark the screen brightness is increased to make it easier to see)

The long piece to the right of it is the proximity sensor as mentioned above, it recognises when you hold the iPhone to your head and turns off the screen to save battery while you are talking on the phone.

Oh. Thanks. It's the first time I have seen it that's all.

And also to cut out touching the screen and ending the call etc unwantedly
