People who have recently bought a new iPhone have been told that a lack of buttons belies a wealth of shortcuts which can be used on the device.
Users can take screenshots which can be saved into their photo folder by pressing the home button and then the on/off button at the same time.
This can come in handy when wanting to make copies of text messages, emails, websites and images which can often be deleted by accident.
Out of the box, the iPhone is set up so that a double-tap on the home button brings up the iPod player.
However, this can be changed through settings, where iPhone fans can choose to have search, phone favourites or camera at the click of two buttons.
Furthermore, users who want to read passages of text through the Safari browser can make their task even easier by double tapping the screen, meaning that the page snaps to fit the screen perfectly.
