Step 5: Install the Find My iPhone app

You can also access all of Find My iOS device's features via the Find My iPhone iOS app.

Accessing this information via computer is all well and good, but what if you're not near a computer when you discover your iOS device has taken a walkabout? Well, as long as you (or a companion) has another iOS device, you can install a handy app that will let you locate your errant device right then and there.

Just grab the from the App Store. (Don't worry, iPad and iPod touch owners: despite the name, it works with all iOS devices.) Once you've done so, you can enter your Apple ID and password and the app will show you a list of iOS devices associated with that account. At that point, you can use the app to do everything that you can do via the Web interface, up to and including wiping your device remotely.

An ounce of prevention
