Future iPhones may act as emergency beacons even without cell service

William Gallagher, AppleInsider:

A new Emergency Power Save Mode (EPSM) will be able to broadcast a distress signal in multiple different ways while also minimizing battery use in order to keep the device working until the user is rescued.

This is from a patent application. No guarantee we’ll ever see this in a shipping iPhone, but I do like the idea.
