K so this should be a pretty easy question Is it safe to update to 4.1? I'm on 4.0u Im softmodded with Softmii 2.1.1 I have preloader and bootmii installed. cIOS Rev 13b I have some illegal wads installed as well. But anyways is it safe to update? And if it is should I use Waninkokos or THE BIG N updater? Thanks EDIT: Yeah so i got a new question lol. I might seem like a total dumb ass. But anyways I see people say that they have bootmii and a NAND back up? What's the difference? Can't I just install bootmii as boot2 and thats my back up?
