When Apple released Find My iPhone as a part of MobileMe and iOS 3.0 last year, it seemed to be a feature that a lot of iPhone carriers would use if they didn't have to pay the MobileMe subscription cost. Thankfully, Apple has made a few changes during the 4.2 update and has turned Find My iPhone into a free app you can download from the iTunes App store starting today for your iPhone, fourth generation iPod Touch, or iPad.
Simply install the app on your iOS devices and you'll be able to find your iPod Touch, iPhone, or iPad on a map, play a sound so you can locate it locally, or remotely set a passcode and wipe its contents if you suspect it's been stolen. The catch? You'll need two iOS devices in order to use the feature. Find out more after the jump.
Apple is assuming that you'll have more than one iOS mobile device in your home and uses both in order to find your missing item. You'll need to install Find My iPhone on all of your iOS 4.2 devices and, for example, use your iPad to find your lost or stolen iPhone (or vice versa). Guess those of you who own just an iPhone (or iPad or iPod Touch) are out of luck for now.
