Shake To Undo is a feature Apple added to basically substitute Ctrl + Z. Seeing as the iPhone doesn't have a physical keyboard they decided that shaking your device was the best way to do it. Well, for me, I find this feature really annoying since I am not doing anything where I would have to "Undo". I don't mind simply hitting backspace or something, I usually relieve I've made a mistake before the next word. Shaking just seems like putting a little too much effort to Undo, this should be a button next to the "auto-fill" option. To get rid of this feature, download ShakeToUndo Killer from Cydia.
