Whether it's an email to your boss, an awkward rejection text for that second date invite, some sage advice for a friend in need, or something equally precarious, there are simply times where you'll need to undo and redo typing seemingly a thousand times before you get the message right. You'll want every single word to be perfect so that your recipient can't misunderstand or take what you're saying the wrong way.
The iPhone has an awesome little inbuilt feature that allows you to undo text in less than a second, thus saving you plenty of time when you're writing long messages. Simply shake your phone and the 'undo typing' option will appear. At this stage, there's no good option for a 'redo' but we don't really think it's as crucial as the undo function!
