iPhone Screengrab Trick

Having been used to doing "Shift Apple 3" for screengrabbing on my desktops and laptops for years and years and years, I was pleased (but a bit surprised in a way) to find out from Cult of Mac that Apple allow you to screengrab your iPhone too...
Dead easy of course.
All you do is hold in the "Home" button (that's the round one below the screen) and click once on the "Power" button that's on the top of the phone. Don't hold it down, just click it the once, and you'll hear the familiar camera shutter noise, and if you then go to the "Camera Roll" part of the camera where you store photos you've taken with your iPhone, you'll find the image there.
And then you just import it into iPhoto.
