thats whats happening to me, i keep getting this "NO TELEPHONE NUMBER" message and it just cancels the phonebook transfer (i used windows mobile, which was a flawless experience before) and with phone like the razr it had duplicate contacts and other issues. now it doesnt transfer at all. THIS SUCKS! it was perfect before this. and also so far the bluetooth sound quality is worse. i hear more noise similar to the ORIGINAL firmware which was unusable. Not as bad but its a step backwards for sure.
is it possible or safe to DOWNGRADE THE BLUETOOTH firmware back?
Yes, you can easily donwg
