Your iPhone can do all sorts of things to make your life just a little easier in ways you probably didn’t know. Here are 21 features you can start using today! From Shake to Undue – to Finding out which planes are flying overhead right now! 

Some might call these ‘hidden features’ but I prefer to think of them as simply undiscovered. Perhaps you have a favorite ‘undiscovered feature you found or use on your iPhone – if so, why not share the love?
