It was news to me.  I knew they use closed firmware, but I didn't 
realize that someone could send a 73 byte command to get remote code 
execution.  I know that the modem chip is separate from the CPU in the 
Neo900 which is great. I'd like to go a step further since I don't need 
cellular access. I'm glad that this will be an option.
