Did you know that you can take pictures of what’s on your iPhone’s screen? For example, you can take pictures of a text message, a web page or an email configuration screen.
The procedure is simple. Press and hold the Home button while simultaneously pressing and releasing the Sleep/Wake button.
The Home button is located near the bottom of the front face of the iPhone. This is the button that you typically press to exit an application and return to your Home screen.
The Sleep/Wake button is the button on the top edge of the iPhone which you typically use to put the iPhone to sleep.
Be aware that if you were to press and hold both the Home and Sleep/Wake buttons continuously for 10 seconds, this will reset your iPhone. Resetting an iPhone isn’t necessary very often, but if your iPhone locks up and becomes completely unresponsive then resetting is often helpful. Resetting the iPhone essentially just forces the iPhone to turn itself off and then start up again. It does not remove any of the data or applications on the iPhone.
The ability to take a screen snapshot was added in version 2.0 of the iPhone software, released in mid-2008. If you happen to have an original iPhone and have never updated its software then you don’t have the ability to take a screen snapshot with your iPhone.
