With the iPhone 2.0 software update (and the iPhone 3G) Apple's made it easy for folks to take a screen shot of whatever appears on the display of their iPhone.

To take a screen shot, simply hold down the Home Button and Power Button at the same time and let go. (Hold them to too long and your iPhone will reboot.) That's it. A white flash of the screen indicates the deed has been done.

The iPhone saves the screen shot to your iPhone's camera roll. Don't be concerned if the thumb nail seems a little burry (see right). Tap it and a nice clear picture of whatever you had on your iPhone's display appears in all its 320 x 480-pixel resolution glory (see below).
