Why use Bluetooth, why not plug it in & let it be recognized as mass storage? I have a Bold 9000 & a MacBook Pro with external Mass storage enabled, I just drop & drop the mp3's or pics to the appropriate folders.
Why shouldn't i use Bluetooth?? While the instrument has inbuilt facility to send or
recieve mp3 data via Bluetooth!! It's easy to use for data moment instead of use data card..
But the OP is having issues with BT. Chika7 merely suggested a practical alternative.
I've found BT to be glitchy on BBs. People are still having issues with BT synching, and sometimes sending files over a certain size doesn't work very well either.
