It may surprise you to know that the iPhone has two microphones and when on a speakerphone or FaceTime call, you're probably talking into the wrong one.
The iPhone actually has two speakers and two microphones. One set is at the top of the device and one set is at the bottom. The bottom microphone is located to the left of the dock connector. The top microphone is located next to the headphones jack.
When on a typical call the bottom microphone is active and the top microphone is used for noise cancellation.
Often when users are in a speakerphone or FaceTime call, and the person on the other end of call can't hear them, they will move closer to the phone and speak towards the microphone at the bottom of the device. Surprisingly, that's the wrong microphone to be talking to. Rather than using the bottom mic, Apple switches off noise cancellation and uses the top microphone to maintain a maximum distance between the bottom speaker and the voice input at the top of the iPhone.
This was new information to us, hopefully you find it useful when making your next call.

I don't know where iClarfied received this article from but it's partially correct. As for the two mics they are correct but two speakers....no way. The iPhone has never had two speakers since the day it was born.

Um yes it has, The iphone 4 always had the two mics. I think it was even mentioned in the iphone 4 keynote that its for noise cancellation, if you open the iPhone and simply look next to the headphone jack closely its more than obvious its a mic

Omg! And you're telling this now?!? I was speakiing all this time towards the little whole on the right side of the iPhone thinking THAT specific hole was the mic! (when I just discovered that it was after all the opening hole of the SIM slot...)

Now does that mean noise canceling is inactive during FaceTime and speaker phone mode? Or does the iPhone uses the bottom speaker for noise canceling during such calls?

I am surprised that iClarified saying this is new to them.....
When my customers saying that mic doesn't work on speakerphone, I tell them speak to the top and it works most of the time.

This is true... but not for all apps. The Skype app for example is using the bottom microphone in both modes.
