iOS 7 includes a new feature called Activation Lock, which makes it more difficult for anyone to use or sell your iPhone, iPad, or iPod touch once it’s gone missing or has been stolen. And it starts working the moment you turn on Find My iPhone in iOS 7. Turning off Find My iPhone or erasing your device requires your Apple ID and password. And your Apple ID and password are required before anyone can reactivate it.
Sometimes it’s better to be safe than sorry. If you’re worried that your device has fallen into the wrong hands, you may want to initiate a remote wipe to delete your personal data and restore your iPhone, iPad, iPod touch, or Mac to its factory settings. With iOS 7, Find My iPhone can continue to display your custom message, even after your device has been erased. And if you do retrieve your device, you can restore it from your iCloud backup.
Whether you’re on an iPhone, iPad, iPod touch, Mac, or PC, getting started with iCloud is simple. For new Apple devices, there’s a setup assistant built right in. And for everything else, setup takes just a few quick steps.
