We wouldn't really say we "have it together" when it comes to remembering where we put our keys / phone / small children, so Apple's announcement of the Find My iPhone service for MobileMe users came as quite a relief. The service just went live, and with a quick toggle of a preference pane in iPhone OS 3.0 the phone is fully prepared for all sorts of lost and found scenarios -- along with acting as an incredibly intuitive (if pricey) stalking mechanism. Find My iPhone works exactly as advertised, giving us a fairly good location estimate from within our lead-lined underground fortress, and sending annoying messages to the phone complete with sound, even when the handset is switched to silent, though unfortunately the sound is a sort of sonar ping that strikes us as incredibly difficult to locate, unless of course our phone is taken by whale. The only other problem is that both the location function and the message service took a couple minutes to track down our iPhone -- not a deal breaker, but we don't know what the hangup could be. After the device is pinged, a confirmation of the event was sent to our MobileMe email address. A live, enthralling video demonstration is after the break.
