What other network connections do you have on the FC4 machine? Are you running a firewall? What is the output of "/sbin/route -n"? A couple of things to keep in mind - first is that FC4 is no longer supported. Second - You will not get usb0 unless the phone is plugged in and turned on. You may also run into problem if you have it plugged in at boot - you may have to unplug it, and plug it back in again, or at least turn off the phone, and turn it back on.
