I use Nokia E66 phone. It runs S60 3rd edition FP1 (aka Symbian 9.2). When I switched to it sending files over Bluetooth was easy: obexftp -b BD:AD:RR:EE:SS:00 -p FILE1 FILE2 and files landed as messages in phone Inbox. But for some time it is not working — all I got was “Sending FILE1…failed” like messages.
Hopefully obexftp tool has some options available so after some tests I got it working. And result is even better as files lands in file system instead of Inbox. The trick is to give path on phone to obexftp: obexftp -b BD:AD:RR:EE:SS:00 -c E:/folder/on/card -p FILE1 FILE2 and files will land there.
Simple, nice and the most important: working :D
