You may have heard of the great app on Apple's new devices called "Find My iPhone." Exactly what it sounds like, the app runs a GPS search for your device, in the rare and sad event that you misplace it. I don't think I had ever used it for anything other than fun (checking on which store my wife went to for my birthday, etc.), until a few weeks ago. My heart dropped when I realized I didn't have my precious phone while on a road trip down south. I could live without email and phone contact for a few days, but I started to panic when I realized what I lost in pictures and videos of my family (should have read up on how to back up my iPhone sooner).
But, once I got out of the boondocks, I was able to connect to WiFi, and you won't believe the story that goes along with my lost iPhone.
