This past week I posted a screenshot from my iPhone to my twitpic account. I immediately had people ask me how I did it, obviously tech nerds don’t read manuals (just like me). I didn’t know it was possible to take iPhone screenshots until my younger sister, an Apple employee, showed me how to do it a few months ago.
To take a screenshot with an iPhone simply press the sleep and home buttons at the same time. The screen with briefly flash and a screenshot will be saved to your iPhone’s camera roll as a PNG. You can get the screen shot off your phone just like any other photo. You will need an iPhone running firmware 2.0 or greater in order to use this feature.
