an ICE number. That means In Case of Emergency, and first responders are being trained to look for it. Just "ICE" and a number.
I have ICE1 and ICE2, my wife and another family contact.
Sometimes I click on the links advertised in tiny type face at the top of the CNet forums screen where it says "On TechRepublic". This time it took me to this handy article...
?Always be prepared!? That?s the Boy Scout motto. Here are 10 phone numbers we could not care less about until the moment we need them, at which point they save us time, money and general peace of mind. Do yourself a favor and take 10 minutes to program each of these handy numbers into your mobile phone. I promise you, the convenience you will gain from it someday is priceless.
I remember a thread we had before, that talked about what numbers should be programed in case of emergency. I think this article expands on the subject quite nicely.
