ICE (In Case of Emergency)
Many bodies like Red Cross and Police request that each person include in his contacts list some ICE (In Case of Emergency) contacts to be used in cases of accidents and emergencies. On the other hand most of the people keep their iphones locked under a password, so even if the iphone was found in case of accidents, the ICE contacts cant be known.
I suggest that a new ICE icon be introduced in the operating system. This icon will be used to enter ICE contact numbers, and these numbers will show on the first screen where "slide to unlock" is shown. This allows the helpers in case of accidents to retrieve these numbers easily and contact whomever the iphone owner assigns.
