Any unlabeled button on an iOS app can be labeled easily

Hi everyone, some of you may already know that in iOS 5 there is a voice over label feature. Whenever there is an unlabeled button in an app, you simply double tap with 2 fingers and hold after the second tap, which then makes a sound and brings up the keyboard, allowing you to write down what you want the button to say. This is also useful for labeling photos. So anyone encounters a great app with unlabeled buttons, if others could post what those are, that would be very helpfull for everyone, because we could all make those specific apps a little more accessible. Thank you for your support, and for more info, please consult the iOS Manual what's new in iOS5 and or Braille commands for the iPhone
