Apple’s Scott Forstall just showed off the previously-rumored Find My iPhone feature in the iPhone 3.0 OS.
Find My iPhone is a MobileMe service that helps you find your lost iPhone, or wipe it remotely.
The service allows you to send the iPhone an alert sound that will play even if the phone is in silent mode — good for finding it in the back of the couch. It will also display a message on the home screen, such as another phone number, in case a stranger found it and the screen is locked. Clever.
If you think the phone has been permanently lost or stolen, you can also wipe all the data remotely. And if it shows up again, you can restore from a backup.
