NetworkManager needs to be rebuilt with support for the new ModemManager
from git master.  Otherwise it only knows about MM 0.6 and earlier.  So
if you're using the stock NM from 12.10, it won't know how to talk to
latest MM.

Best thing to do there is to use the mmcli commands as Aleksander
suggested, so we can see if everything works correctly.  Then you can
move on to using an NM PPA or something to get a more up-to-date NM.
