I haven't seen this anywhere... and I'm not sure if it's from the 2.0 firmware or if it's been around forever. If you press the home button (the circle one at the bottom) and the power button together, it takes a snapshot of your current screen that saves it in your photos app. Anyways, I thought it was cool and perhaps helpful for those that did not know about this. If so, I apologize for the repost
