I searched the forum and could not find a solution or a post. Why is it that when someone calls me and I'm currently on a call, the party I'm talking to can hear the call waiting tone? The other party actually ask me if I need to pick up the other line. When in a conference call or other important phone call, this is very obnoxious. I did not have this problem with my 2G phone. I have tried restoring the phone with no success. I called Apple but they did not have a solution.
