Recent versions of NM (0.8.1) and MM (0.4) will request the PIN to
unlock the device when the device is plugged in so the SIM won't get PUK
locked there.  We still do need to get a better way of tying a cached
PIN code to the specific SIM card, though this isn't possible for a lot
of devices that don't allow access to the SIM's IMSI until you've
entered the PIN.  Some devices do allow it though.
