Mic works, but other party can't hear me on calls?
Ok, my iphone 4 has, just in the last 24 hours, began an issue where on a call, i can hear others, but they can't hear me. This isn't an issue with the mic, as on more than one occasion i have used the voicedial function to begin these calls. I've also cleared the headphone jack with compact air. It's really annoying as it's just passed it's warranty date. Help!
