Well will freeshop still be OK to use
The risk of getting banned by using CFW remains the same.
If you've been banned-free this far and hadn't done anything obvious like cheat in online games, played games before their official release, or use homebrew CIAs [this one is a toss up], you're fine in using freeShop.
If you want an anecdotal story for comfort, my N3DSXL was updated the second day 11.7 came out, and I have been using
freeShop everyday, which is
freeShop injected into
eShop using GodMode9 script injection. If I was Nintendo, I would ban myself the first moment I knew
actual me insulted my store front with a pretender app. Okay, that came out super confusing, but basically I'm not banned. Stick to using the
freeShop.3dsx version through Homebrew Launcher if that's what you been using.
Update away.
