Lose Your Apple Device, Locate it for Free

Apple released a new version of iOS on Monday, adding new features to the mobile operating system that drives the iPhone, iPod Touch and iPad.

Owners of the iPad, a camera-equipped iPod Touch or iPhone 4 can go to the App Store and download Find My iPhone. The service was previously included only as part of Apple's Mobile Me package, which costs $99 per year.

Once the feature is enabled, the owner of a lost device can see its location on a website, which accesses the phone's GPS coordinates to show it on a map. You can also have the gadget display a message pleading for whomever finds your property to return it; additionally, you can set a passcode or send a command to wipe personal information from the hardware.

The update also adds the ability to wirelessly print documents and to transmit video or music to an Apple TV or compatible speaker system using a feature called AirPlay.

This software version 4.2 brings the iPad in line with Apple's other mobile products. With this version, the iPad can now run apps in the background -- say, listening to Pandora while surfing the Web. It also unlocks Game Center (Apple's social network for games), the ability to organize apps into folders and new features for e-mail users.
