In version 2.0 of the iPhone/iTouch software, Apple has added screen capture. If you need to get a clean image of your screen for that next article, press and hold the home button and click the on/off button. The screen will flash white and you will hear the same familiar camera click sound that is heard when doing a capture on a Mac.
Have fun/torment your friends with this: ask to look at their iPhone, do a screen capture of their home screen, navigate to photos and click on the image of the home screen, wait for the photos navigation to disappear and hand the phone back to your unsuspecting friend. He/She will see their home screen but it will not interact as it is just an image.
Hilarious... or dangerous depending on the friend.
