Apple has issued a minor update for its Find My iPhone app, adding driving directions to device locations. Several buttons, namely Play Sound, Lost Mode, and Erase iPhone, have also been removed from the map view and are now shown on the device info screen. Find My iPhone is a free service that lets MobileMe subscribers track the location of an Apple device, as well as send message and sound alerts directly to the device. An option for remotely wiping the device adds additional security for those afraid of having confidential data compromised.
