Haha, interesting.  I guess we shouldn't CFUN=0 Nokia phones...  will
have to fix that.  Any chance you could file a bug about that at
http://bugzilla.gnome.org with this modem-manager debug log and assign
it to the "modem-manager" component of the NetworkManager project there?
That helps make sure it doesn't get lost forever on the mailing list.
