I stuck a pin into the noise-canceling microphone with moderate force although it didnt go very far down. I realized what I was doing and then corrected the lady about where the sim card tray is on the iphone4. anyway, what are the chances that I damaged the noise-canceling mic by doing that and how would I tell if I did?
