    Are you covering the microphone with your finger, hand or a case?

    I also has this error. My Iphone 4 worked like a charm and then the microphone suddenly goes silent. It´s possible this started when i upgraded to latest firmware 4.2.1.

    I can sometimes get it to work with a handsfree but when I pull it out the microphone works for 3sek and then goes silent.

    In diffrent forums I have read that this is a common error but I can´t tell if its a hardware or a software- problem.

    The problem happened with firmware 4.1 and after updating to 4.2.1
