If a missing online iOS device is nearby, play a sound on it to assist with finding it.
Securely lock an online iOS device and display a custom message along with a contact number. The finder of the device is able to call the contact number from the device itself.
If the online iOS device is lost or stolen, it can be remotely erased, removing the personal info (e.g., contacts, email, music, etc.) and settings to prevent anyone from seeing or using the info.
If an iOS device is no longer being used, it can be removed from the Find My iPhone devices list.
