Like the name of the thread says, I'm planning on getting a flash card. And I've heard a ton about gateway, and how it has region-free, homebrew support, ability to download eshop games for free (or something like that), and the like. Then I see videos showing off DevMenu, or whatever it's called. And the ability to backup your sysNAND (if I understood it correctly?) and restore it, kinda like what BootMii does back on the Wii. My system is currently running on 9.2, and I've left my 3DS off just so it can't update. With all the things I can do, and while it does tempting. It also looks like there's the risk of bricking. So, what exactly can I do with the gateway card, before I make take the leap of faith to actually get/use one.
