Introduction to Setting Up Find My iPhone
If your iPhone or iPod touch has been lost or stolen, it's not necessarily gone for good. If you set up Find My iPhone before it vanished, you may be able to get it back (or at least keep the person who has it now from accessing your data). It's crucial that you enable Find My iPhone before your device goes missing. After it's already gone, it's too late.
Find My iPhone is a great tool for finding lost or stolen iPhones. It uses the built-in GPS or location services of your device to locate the device on a map. It also allows you to lock or delete all data from your device over the Internet to prevent a thief from accessing it.
