This is a really weird deal. A friend of mine got an Epic about the same time I did, and we talked a lot, with both of us using speakerphone, and it sounded great. But at some point it started messing up, when both of us were on speakerphone. We get this really loud chirping sound, that goes away, if one of us turns speaker phone off. My friend also has this problem when talking to his wife, who also has an Epic. I don't experience any problems using speakerphone during any other calls, nor does he, unless they are Epic to Epic with both parties using speakerphone. Just wondering if anyone else has experienced this odd behavior with their Epic? And if you haven't please try to test this out, with anyone else that has an Epic. At this point tech support doesn't have any other feedback, so I'm alone in the woods on this one.
