I bought a Switch a few days ago before it occurred to me that there was probably a homebrew community going, so I didn't take into consideration which switches are patched or not. My serial number starts with XKW and all the checkers online all start with XA(insert third letter). I looked up XKW and apparently that means it's the new switch with improved battery life. I can only assume that this means it's patched. Can I get someone to confirm?
