** Description changed:
In LTE mode, the sierra modem (MC7710) gives no indication of signal
quality in nm-applet. It looks like icon "gsm-3g-none.svg". I suspect
this is caused by this in the modemmanager debug log when connected:
modem-manager[25672]: <debug> [1349256755.558392] [mm-at-serial-port.c:334]

5,0,1,1,0,0,1,0<CR><LF><CR><LF>OK<CR><LF>'
- The signal is good (I measure download rate of 37 mbits/s), and in 3G/2G
- mode I get the correct signal quality indication.
+ Seems like the signal quality is the second number:
