Running the new iPhone 2.0 software? Want to grab a screenshot of something? Turns out it's amazingly easy. Hold the Home button down, then tap the power button on the top of the phone. The screen will flash white, and that's it -- the screenshot has been taken.

Open your iPhone's Photos app, and you'll see the just-taken photo in your image library. This works amazingly well, and it's nice to see a factory-bundled solution for those of us who write about the iPhone!
