have either of you taken one apart???
no, i have and there is not a way of telling
and have you not heard the stories of people getting replacement 360s that have been banned already??? you know why? because MS doesnt check, i personally know two people who have replaced their banned 360s for unbanned ones, and i know of people online doing it too
and if MS does realize it, you have already gotten your replacement and they wont say "hey ship the good one back", they will simply unban the console they have
