Yes, this is exactly what I was thinking, the actual firmware cannot and
will not be open sourced, however, other companies allow firmware 
updates to load firmware created by the manufacturer, just as they do
for GPS receiver modules and many other devices. You can update 
firmware, even as an end user, much in the same fashion as flashing
a bios on pc, for most products like this. So although we know the 
firmware for things like gsm, gps, bluetooth, wifi will not be open 
source, long term it would be best if FIC worked towards using 
modules that can be field updated by users.
