Did you know that the Undo command is also available on the iPhone and iPad?  When you are typing an email, or a text message, or practically anywhere you are entering text, simply give the iPhone or iPad one good sharp shake forwards and backwards. Suddenly, in the middle of your screen, the Undo option will appear, along with a Cancel button if you do it by mistake 🙂  Just hit the Undo button and whatever you last typed will be un-done, including any text that you might have deleted by mistake! Remember, if you hit something by mistake and text disappears, or something happens that you weren't expecting, all is not lost!  Try using Undo,  it could save your day to play the game!
