About a week ago, my 770 stopped "seeing" available bluetooth phones with which to pair. I have since tried at least 4 different phones, and every time the 770 simply states that there is no phone detected. At this point, I am convinced that the problem lies with the 770, and not the phones. I have already tried re-flashing my 770 with the Windows program to no avail. Is there anything else I can do on my own to fix this problem? I would hate to send it back to Nokia for warranty repair, as I am sure that it will take at least a month to get it back, and it works in all other respects. Thanks in advance for any helpful responses!
