I got an email from England over the weekend with a suggestion in it. I opened the British paper this morning, and there was an article about the email I had recieved. Link
Put an 'In Case of Emergency' number on your cell phone's phone book. The number of someone you trust, they don't have to be related to you...just someone who knows you and who knows that you have them listed as your emergency contact.
Ever since I had a bad car accident a couple of years ago I've carried a slip of paper in my purse with my emergency contacts on it. I have another one on the glove box of both my car and my Jeep....it just never occured to me to put one on my cell phone.
ICE your cell phone. I'm ICE-ing mine right now.
