SBAdblock Toggle is the name from modyouri, to be specific. I use it, and like it a lot. I wish they would make it into a full fledged GUI that would work like AdBlockPlus does on FF. I'd love to be able long press over a frame or image and have the option "block image" or "block frame" or whatever. SBAdblock Toggle works by using an SBsettings toggle that switches between a modded and unmodded hosts file. Also, it will patch popular tweaks like SBSettings, by tap and holding the toggle, so that one can access the more app and not have the pesky "adblocking hosts file detected, fix?". I understand the purpose of ads in free apps, and try to use the modded hosts file while on 3G.I don't mind "accidentally" clicking on ads every so often so I can support these rockin devs!
