Mounting the memory card on your mobile phone over Bluetooth is now really smooth under Fedora. Thanks to topyli’s post and David’s HOWTO, all you need is the one-liner below. Once you’ve paired the devices, and have installed obexfs, and fuse-utils, run this, and your read to copy files:

NAME="MY PHONE NAME"; MAC=`hcitool scan | \
grep $NAME | tr '\t' ' ' | cut -f 2 -d ' '`; \
CHANNEL=`sdptool search --bdaddr $MAC FTP | \
grep "Channel" | tr -s ' ' | cut -f 3 -d ' '`; \
obexfs -b$MAC -B$CHANNEL /mnt/phone

To unmount:
fusermount -u /mnt/phone
