Introductory text on typical GSM phone hardware

Hi! While working on OsmocomBB, I wrote a small introductory text explaining how current GSM phone hardware actually looks like (and works). You can download it from http://laforge.gnumonks.org/papers/gsm_phone-anatomy-v0.2.pdf Hope this is useful for one or the other person here on this list...
