yeah but tbh people have a tendency of not warning people or keeping their console in a safe place and then wonder why someone updated their console.....yeah sky3ds may be safe for now, but should a block arrive for sky3ds it will be exactly the same situation.......people just need to learn to warn people or dont let people have access to their console, i have leant my 3ds to my nephew who is 7 and he managed using the gateway card perfectly fine......its just people who are unaware of the situation being expected to know that the owner wouldn't want to update, most people just assume they are doing you a favor
articles like this don't help
http://gizmodo.com/important-psa-update-gadgets-before-you-wrap-them-1487186506 , yeah imagine the look as you get handed your nice new n3DS (yes im aware thats 2 new's) and they say "oh and i updated it for you so you can go straight to playing"....and you have to sit there and say thanks for that lol
