Well, no matter where I go or how many times restart, when I'm in a call, I can hear them, but they can't hear me. I did drop my phone the other day and thought I may have screwed up my microphone/receiver. However I tested this with the onboard voice recorder and sure enough, the recorder picked up everything just fine. After more troubleshooting and even more interestingly, when I hit the speaker button while in a call (turning it blue/active) and thus enabling speakerphone, they can hear me just fine. When I disable speakerphone, they can't...as if it were muted.

Am I missing something here?

    I too I'm having the same problem with my iPhone 4. Initially, I could not make or receive any calls or messages.Took phone down to the T-mobile shop and they tried the sim card in a HTC Hero and it worked fine. This ruled out a network problem. Called up Apple and they sent me out a replacement handset that arrived today. I put the sim in and set it up as a new iPhone. This time I could make & receive calls but like Zathrak the person on the other end cannot hear me. I called up Apple services and they asked me to test the mic with the voice recorder and it worked fine.They ask me to set up a new itunes account under a another user on my PC and then set up as a new phone again. This has also failed. Booked in to see a 'Genius' at the local Apple shop tomorrow. they say it could be a software fault. That's 2 iPhone 4's in 4 weeks!. I didn't have this problem with my 3GS. At least there is somebody else with the same issue.

    For anyone experiencing this issue, schedule a date with "the genius bar," go to the nearest apple store, have the "genius" hook up your iphone to their little diagnostic tool, it won't pass, they'll issue you a "new" iphone (free). Problem solved.
