Did you know that “shaking” your iPhone is a short cut for a few different tasks:
1. If you have just typed in a message and decided that you wish to delete it, just shake your iPhone. A pop-up message will appear asking if you would like to Undo Typing, or Cancel.
2. If you have pasted a piece of text or an image and want to undo it, then just shake your iPhone. A pop-up message will appear asking if you would like to Undo Paste, or Cancel.
3. If you are listening to music on your iPhone, you can simply shake it and it will immediately change songs as it does when you are in shuffle. Shake anytime again to change to another song.
