I have been reading that many people are actually worried about using a flashcart and the ds system updating later on at some point. This will report the games like ( fish tycoon) was played for 500 hours to nintendo and supposedly brick your system because they know that your using a supercard ds two for example. We can go on and on here about that, but i was looking at those pictures of the take apart of the 3ds and did you notice in the pictures that with the proper screws you just need to remove the back panel off the the 3ds? its as easy as changing batterys on your remote! the point is you can just disconnect the antenna from the wireless card, without having to remove the card itself so that the system cant be detected by wi fi services. of course it would render online services out of the question, but it would secure you from any updates that ninendo puts out. i looked at the pictures posted a few links below this one and it looks easy enough to detach the antenna even better, maybe a new type of mini pci -e card could be used to replace the wireless card kinda like a mod chip to prevent any future crap nintendo might put out. Hardware before software i always say!
