This handy keyring is in fact a portable sim card remover for the iPhone! Simply push the little button on the bottom of the device to release the 'padlock' and reveal a small prong - perfect for releasing the sim tray at a moment's notice!
Gone are the days of searching for your iPhone's official sim pin (has anyone actually managed to keep hold of that blink-and-you-lose-it bit of kit?!) or untwisting a paperclip to use as stand-in sim tray remover. Simply attach the App Lock to your keys, bags, clothing, or even the handset itself, and 'unlock' it when you need to access the iPhone's sim card. Easy!
