I went to a party last Saturday and when I got out of my car I must have dropped my iPhone on the ground.  I did not realize it until a couple of hours later when I was going to call a friend.  So I retraced my steps and when I got back to where my car was I saw my phone on the ground.  Luckily no one had stepped on it or there was no rain storm.  I picked it up and put it in my pocket so that I did not lose it again.  Now I make sure I have it in my hand before getting out of my car.
