As part of Apple’s MobileMe suite of everywhere email, calendar, contacts, photo and online storage space, Apple has tucked away a wicked cool feature: Find My iPhone. Apple has made the feature available via a browser for a while, but now Apple is offering Find My iPhone as a free app for iPhones, iPod touches and iPads. The app does what it says it does — it finds your iPhone if you lose it — with some caveats. First, if you install the app on your iPhone and then lose your iPhone, the app doesn’t wake up and phone home.
