If you haven't seen the entries floating around already, you can take screen shots of your iPhone with the new v2 upgrade.

To take a screen shot all you have to do hold down the home key (bottom square button) and push in the top button. The screen then will flash for a second then you're done. You'll find the image on your camera roll where you can sync it up to your Mac/PC and do what you want with it.
