probably an ambient light sensor.

That would be the light sensor. It brightens or darkens your screen depending on the surrounding light source(s) it senses.

That little circle just happens to be the iPod's Ambient Light Sensor (ALS). It isn't very effective on the iPod for some reason, but all it does it adjust the screens brightness based on how much light is in the room you are in. (More light = brighter screen, less light = dimmer screen.)

It's the light sensor for auto brightness...
