The Find My iPhone (or iPad or iPod touch) feature is now free to use without a MobileMe℠ subscription and helps you locate your missing device.* The Find My iPhone app is a free download on the App Store℠ and lets users easily locate a missing device on a map and have it display a message or play a sound. Users can even remotely lock or wipe data from a lost device to protect privacy.
*The free Find My iPhone feature is available for iPhone 4, iPad or new iPod touch (4th generation).
You can still use Find my iPhone on older iPhones and iPod touches but the account has to be set up on a 2010 model first. Either express your delight at having the new free service -- or your outrage at being inconveni -- in the comments!
