Has anyone had any problems with a "chirping" noise in their phone? Callers say that when they are talking to me, they hear a loud chirping noise. Does not matter if they are calling from a land line or a cell, this chirping noise gets so loud sometimes that they have to hang up. I have the new Blackberry Storm. I called tech support and they sent me a new phone, but the same thing is happening. Can anyone account for this or had this problem?
