It fell out of my pocket when I was walking from where I eat lunch to class and it was gone by the time I checked (walked back, looked in halls, blah blah blah) less than two minutes later. Someone picked it up.
That sucks. :( I hope I don't lose mine (whenever my game actually gets here) because my phone already dropped out of my pocket once and fell in the car. I never noticed and thought I lost it in the bowling place.
