Apple has made some adjustments to the must have Find My iPhone app, including some UI improvements and a new button layout.
One noted update in particular is the addition of driving directions to the location of your device. Just tapping the green car icon on the map will link you to the Apple Maps app with turn by turn directions to your device. Now the question is, will the directions be accurate? (Insert iOS 6 Maps joke here). But seriously, I think this can only be more helpful to users looking to recover their most prized possession.
Find My iPhone is free to download in the App Store.
