iPhone 4 - Microphone Failure / Crackling Audio

[harcosparky]

More times than not when I make or accept a call the microphone is not working. At other times crackling can be heard in the earpiece and the person on the other end hears the crackling and broken up audio from me.

My son said he read somewhere of a short developing in the corner of the iPhone where the headphone connector/noise canceling mic is located. Something about a short in the noise canceling mic circuit shutting down both mics.

Anyone experience the problem as I have described, if so how was it repaired? ( other than getting a new phone )

Thanks


EDIT: Other then this audio problem the phone works fine.
