Here is how you take an instant screenshot with your iPod Touch or iPhone. You don't need any software for doing that. Just hold down the Back Button or your menu button and press the power button at the top of your device, a flash will appear and the screenshot has been taken and saved to your Saved Photos folder. This is so cool and easy to use. This is not a hack but an in-built shortcut by Apple.
