So I own an original Japanese language 3DS that hasn't been updated (or pretty much touched at all) since production. I don't know an ounce of Japanese, so I've been using this nifty smartphone app to translate the menus. Obviously, a region unlock would be desirable for me. The firmware version is still "Ver. 1.0.0-0J." However, it seems like a lot of applications, such as the web browser and the 3DS Store, are not functional on this firmware. When their icons are pressed, I am greeted with a dialogue that roughly translates to, "This feature will come in a system update." I have no idea how to update the system, but assuming I could figure it out, would it be worth it? Is there a significant probability that updating the system will invalidate me for any upcoming region unlocks? Is there any disadvantage to staying on this firmware if I don't care about web browsing (I do, but assuming I didn't)? I understand that the question is subjective; that is why I am posting it on a public forum for discussion. EDIT: I've done some reasoning, and the question has changed; please refer to post #4.
