I'm having an issue that just started today and the folks at Sprint cannot seem to give me any ideas to what could be causing this. What is happening is that when someone calls, they can hear me, but I cannot hear them. If I make any calls, everything is fine. This is also happening to my wife's phone as well and she is on the Epic 4G Touch. Sprint says that there is no outages and see's nothing on my account. I have done the usual troubleshooting...took the battery out, updated PRL, and updated profile. Any thoughts on how to fix this issue?
