Can someone explain to me what is a cellular layer? If it's enabling making phonecalls on the N800, i doubt that with the current hardware. Unless Nokia has hidden phone hardware and a SIM slot somewhere in the N800 like they did with the FM radio.
If you talk about making phonecalls from the N800 by using a separate mobile phone, what's the point? Can't i just use the mobile phone in the first place?
Or are we talking about something else?
