    It has a 2nd mic for noise cancelation BUT

    the second mic looks like it is located on the keyboard. How effective would it be while the keybaord is closed?

    Does that mean we have to have the slider open to take advantage of it?

    Not a problem. It is near the split between the two halves. All it needs to do is pick up ambient noise, so it could be located almost anywhere.

    The way noise canceling works is to have two mics in different location to pick up the sound and then cancel out the sound that is common to both (ambient noise). This way only the speaker's voice is amplified and sent over the transmitter.

    Typically the two mics are on two different sides. This has a side effect of being able to utilize the noise canceling mic as normal source as that the mic is closer to the source and the normal mic becomes the noise canceling mic in that instance.

    It will still be able to pickup sounds which is all that it needs.

    I thought it was on the backside of the Pre^3...

    Ideally, you would want the noise-canceling mic on the back side of the phone... because you are trying to pick up the outside noise that is not coming from your mouth.

    We know what you are talking about... and it will work just fine. I can post that again if that will help you believe it.

    I never figured out where the second mic port was. It's possible that is the actual microphone, and the second one is located in the area of the speaker phone speaker.

    It will be fine. These guys have designed a few mobile phones.
