Yes, it's hidden, because NM 0.7.1 doesn't have the infrastructure to
support that. Please see:

http://blogs.gnome.org/dcbw/2009/03/20/thats-when-i-reach-for-my-revolver/

basically, *every* vendor implements the prefer 2G/3G command
differently, which is quite annoying.

This functionality is supported on the NM 'master' development branch,
which uses ModemManager, which has a plugin architecture that allows us
to special-case whatever crackrock commands the OEM decides to impose on
users.

Seriously though, I can't believe there are like 5 different AT commands
for setting 2g/3g preference. It's not that hard a thing to
standardize, but I guess the 3GPP got caught with their pants down.
