How to clear iphone memory
Look for the sleep/wake and the volume buttons.
The sleep/wake key-the one that you use to lock and unlock your iphone screen-can be found on the top side of your iphone. The volume keys can be found on the left-hand side of the device.
Press down the sleep/wake and the volume keys. Keep your fingers pressed on the two buttons for at least 10 seconds or until the screen shuts off.
