Do You Know Where Your iPhone Is?

Find My iPhone is a free app (for iOS 4.2) that allows you to track the location of your iPhone or iPad. If you lose your device, you can log into MobileMe, and play an alert (maybe it’s just fallen under the bed?) or lock the device with a four-digit PIN or even wipe all your data off the device, so it doesn’t fall into the wrong hands.
