Update: the release of the homebrew loader will be delayed due to the soon to be released new 3DS (which is actually pretty cool, as it's kind of what the DSi was to the DS, with upgraded hardware, better design, etc). Hopefully the exploit will work on that 3DS as well so the homebrew loader can be released asap!
