Just for my understanding: I thought that on my openmoko-phone even the 
hardware is supposed to be free and open. How can it be than, that there are 
"hidden commands" and NDA's?

I read somewhere (long time ago - before the FR reached its birthday) that 
there might be some pieces of hardware not open such as the GSM chip. I guess 
exactly this is the case. Could someone experienced to NDA's, copyright laws, 
GPL violations and so on please explain me how exactly this is handled here?
