I was having this problem as well. I checked the microphone with a flashlight (which is the small whole that's at the bottom of the phone, next to the USB port), and I noticed that there was some crap in it. I used a needle and removed it, and that did the trick. People can hear me perfectly now. BUT BE CAREFUL NOT TO GO TOO DEEP WITH THE NEEDLE, you might damage the microphone.
