[FW 2.x] - etc/hosts now works, can be used for adblock in safari
It looks like MobileSafari is now referencing the HOSTS file for DNS resolution first/finally. This allows us (among other things) to start blocking certain ad sites by 127.0.0.1-ing them out... giving users a rudimentary AdBlock feature.
( don't think anyone has mentioned/noticed it yet, ignore if it has been talked about )
