When the information is obtained from the phone company ( in this case
   MCI)
   for "untraceable" phone calls, what kind of data will I receive?  Is
   there
   ever any way to break this down to something usable?  My problem is
   harrasing
   phone calls that appear to be coming from out of state but I believe
   are
   actually coming from a cell phone is state.  Any ideas or helpful hints
   would
   be very very appreciated.
