In addition to releasing its new MobileMe Mail service on Friday, Apple also released a new Find My iPhone app. Find My iPhone works for both iPhones and iPads, according to Apple. If you lose your device, you just install the app on any other iPhone, iPad, or iPod touch, and then sign-in with your member name to find it.

Apple says you can even remotely lock the missing device to protect your privacy, or wipe it to permanently delete all of your data if you think that it won’t be returned. That service is not available in all countries.

The Find My iPhone We app on MobileMe also displays your device location on a full-screen map.

The Find My iPhone app is available from the App Store for free download.
