Hey all, I've recently noticed this problem on my new white iPhone 4S 16GB. The nature of the problem is as follow: 1.I place a call by tapping on a person's contact. 2.The iPhone goes into a Calling... screen. 3.While on that screen, I hear a 3 second static noise that can be heard from the earpiece before the call starts ringing. 5.Often when the receiver answers, he/she cannot hear my voice at all. 6.However, they can hear me when they are the ones calling me. Keep in mind that I checked if I pressed mute or speaker by accident and it was not the case. I did a restore to my backup and it did not fix the problem. I did a restore and set up as a new phone, did not fix the issue. So I think it's safe to say it is not a software related problem. I tried calling with all apps closed and siri disabled, did not fix the issue. Tried reinserting the sim, did not fix the issue. Is anyone having the same problem or have any insights as to what is the cause?
