White iPhone 4 Different?!

[Mufasa804]

I was on Apple's website and I don't know if you guys noticed this but the white iPhone 4 has like this extra speaker like slit on it's face. What could this be for? I never noticed it before until now.

Proximity sensor and ambient light sensor.

It's the proximity sensor. Been discussed in the other 25 threads.

I thought it was for the super module that solved the antenna issue...

New...because none of the previous iPhones had proximity/ambient light sensors.

No, on the MacBook and MacBook Pro the ambient light sensor is a little dot next to the camera. It's not the camera itself.

The rows of dots are so the proximity sensor can see through the opaque white glass.
