Alessandro, the default desktop install provides both bluez-gnome and obex-data-server, so you don't have to manually install anything.
If you have gnome-bluetooth and/or gnome-vfs-obexftp installed, remove both packages. According to your screenshot, the phone seems to be mounted okay by gvfs (and obex-data-server), but no files are shown. I'm able to successfully mount Nokia 6230i phone and browse its files.
Could you try doing:
$ killall obex-data-server
$ obex-data-server --no-daemon
in a console, then connect to your phone using the bluetooth applet and attach the console output as a file.
