This has been happening for the last 3 days. I make or receive a call on my iPhone 4 and within seconds the party on the other line cannot hear me at all. I hear them perfectly but they cannot hear me. Sometimes it happens right away sometimes it takes several seconds but my voice completely drops out. This happens 50 to 80% of the time.

Went to the apple store and they checked it by using the recorder app which worked fine and then by making a call which also worked fine. They did not perform any diagnostics. I'm on the road all day and my business depends on my phone. I am now afraid to make calls for fear of the person on the other side losing me mid sentence or not hearing me at all. Sometimes it works, sometimes it does not. This happens whether I'm on speaker, mic or bluetooth.

I upgraded to the latest software on Sunday and to no avail. Am I alone? 32gb iPhone 4 4.0.2 software. Any ideas?

Could this be iPhone problem or ATT?
