I purchased an iPhone 4S in October and absolutely love it, but I am running into a strange technical problem.

People on the other line often tell me they hear a terrible screeching sound or chirping during calls. I no not hear it on my end.

I took the phone to an Apple Store last week and they immediately replaced it. Unfortunately, the replacement model is doing the exact same thing. The problem occurs with and without wifi turned on, in indoors and out, with a low signal or a full five bars. It's seemingly random.

Has this problem happened to anyone else? And if so, did you pinpoint a cause?
