True but the news will cover the announcement tomorrow. I remember CNN and local news networks were talking about the announcement the night of the keynote.
I turned it off the first few months when I gave my mother an iPhone. Now she is running 2 keyboards. If I remember correctly you go to: settings>general>keyboard>auto-correction OFF and I think also check spelling OFF, either it was both or just auto-correct off. I think if you leave check spelling on it might be the same as the tweak don't really know.
