I lost one of my BlackBerrys by a railroad bridge I was photographing once. It was maybe 30 miles from my home, and I got all the way home before I noticed it missing. I logged into BlackBerry Protect, and it located the phone and superimposed it over a satellite image of the location.
I drove back to the site, and there was the phone, right where they said it would be, in some bushes along the tracks. I was pretty impressed.
