I have some 3DS downgraded and pending, waiting on an SD card. I haven't setup emunand yet and it relies on browserhax alone. I heard the browser will update against your will, once 10.4 comes out, with a message saying "Your browser is out of date". Then that will be the end of browserhax on 9.2. Should I worry, will tubehax DNS block it from happening altogether, while giving browserhax support?
