The Gateway 3DS team apologizes for making you guys wait, but it has come back with news about a new user interface based on the feedback left by its customers and users. You will have access to backing up your NAND, user diagnostics, backing up a game, and more, scheduled to be released in the next part of their two part update, according to their email.
This should be a fun new update. I can't wait to see where it goes.
