I HAVE INSTALLED IN MY NOKIA E71-1. IT WORKS FINE BUT IT ONLY SHOWS A LIST OF MESSAGES FROM THE RECEPIENT. MEANING, IF YOU SEND SAY 10 SMS TO A AND RECEIVED 10 REPLY FROM A, WHEN YOU GO TO CONVERSATION, YOU WOULD SEE A LIST OF 10 SMS THAT YOU HAVE RECEIVED FROM A. IT DOES NOT SHOW YOU SMS THAT YOU HAVE SENT TO A.
