Just incase anyone was wondering why they get this error message and cant send informaiton from one phone to another using bluetooth it is because the recieving phone has to be in the recieving mode for bluetooth. I.E. "Recieve using bluetooth". here is a link to help explain..for pearl 8100 users this option is in the folder to which you would like the picture, video, music, or ringtone sent.. once in that folder hit the options button and scroll down to send and recieve bluetooth and ofcourse hit send or recieve for whatever you may be doing at the time.
