Hey, Newbie here to DS stuff. My kids have 3DS's one is at 4.5.0-10U and the other is at 3.0.0-6U. I just got the R4i Gold cards since I know they support the newest firmware(4.5.0-10U right?). The question I have is about the one that my one son did not update. Do I leave it at 3.0.0-6U or do I update right now while the newest version is supported before they push a newer update that is not?
