Take a Screenshot
If you want to take a picture (screenshot) of something on your iPhone, there’s a way to do it. Just press-and-hold the Home button and then press the Sleep/Wake button at the top right of the iPhone. The screen will flash white for a second (like a camera flash), and whatever was on your screen at the time will be saved to your Camera Roll as a PNG file. You can then email or text that file to someone, tweet it, print it, or sync/download it to your computer the next time you connect your iPhone to it.
