Ive been using this for the past few years.  I think its a great idea for our personal phones and our work phones.  Hopefully it will never have to be used, but just in case:

You just pop ICE and a contact number in your phone and should you be in an accident, the Emergency Services can easily see who to contact.  I put ICE and my brothers name with his number so that they know who they are contacting.

Please do pass it on.
