Remember that cellular mobile broadband doesn't actually use DHCP at
all; the DHCP or PPP session is between you and the 3G device itself.
What happens over the air is not DHCP, but a GPRS PDP context setup
between the 3G device and the network that does not include the domain
name.  You *may* be able to obtain a domain name through reverse-DNS,
which NM may already be doing if you haven't set a persistent machine
hostname through /etc/hostname or wherever.
