Well, the problem is everyone is waiting for the private key to be leaked. The issue with getting this (if I remember right) is the 3DS uses a form of a NAND chip which is very difficult to desolder/resolder. If I remember right, TeamTwiizers (the guys who basically allowed everyone to hack the Wii with Twilight Princess) have only shown us they are capable of desoldering a NAND chip of the type the 3DS is using. I believe in them, though. Neimod has made a hardware and de/resoldered the 3DS NAND chip in order to view the RAM though, which may allow the private key to be leaked at the end of the year.
ps Y U SO IMPATIENT? Nintendo's shown us some fun games so far, so give it some time to breathe man.
