I Saw this news from http://www.modchipfactory.com/news/...ds-firmware-has-been-updated-to-620-a-39.html as well. Shit ! Anyway,at present, the best choice is not to update our console.
yeah, I know, accoding to http://www.modchipwarehouse.com/blog/3ds-system-software-upated-to-version-6-2-0-12u/ , this updation also blocked all flashcart, and dstwo has been blocked again, So DONT UPDATE yet if you want to play on your DSTWO until we get a new update.
Owner of a Gateway 3DS card here, and it is working great on my 3DS XL(version 4.5), so dont update your console if you want to play 3ds games through a flashcart. FYI, I got mine from http://www.r4flashcart.com/13-gateway-3ds-flashcart-play-3ds-games-on-3ds-xl-3ds.html which is a really good place.
