Phone case for Atrix - where is the noise cancellation mic?

[artmann]

Just ordered the Atrix. It is not here yet but I want to get a cheap generic case for the time being.

I know where the mic is at the bottom, but is there another one for the noise cancellation? If so, where is it? I want to make sure the case I am getting doesn't cover the second mic, if there is one.

Also, where exactly is the light sensor for the screen?

Thanks.

I believe it's on the back.....that hole next to the on/off print reader button.

That mic is also used when you activate the speakerphone
