Shake to Undo and Redo Typing on iPhone
I finally got around to installing iPhone 3.0 on my iPhone 3G and I’m pleased to discover some of the new features available, but I must say the one I’ve found myself using the most (other than copy/paste) is the ability to shake the iPhone to undo and redo typing in any place where you have inputted text, this is basically the equivalent of Command-Z and Command-Shift-Z in Mac OS X. So cool! I’m pretty thrilled with the iPhone 3.0 OS update, and there are a ton of features and tips out there, check out some more here.
This trick still works in iOS 7, so it’s here for the long haul.
