Phones use the OBEX protocol, so you definitely need an OBEX server. The problem seems to be the initial pairing which must be done for the Pi to show up as a share destination. I have a Bluetooth library on github with an OBEX server that will not reject a pairing request, so might be worth trying. But best solution would be to find out why the Pi rejects the pairing.
