Haiti Earthquake survivor uses iPhone to survive
MSNBC and the Today Show report on the story of American filmmaker Dan Woolley, who was trapped under rubble by the Haiti earthquake and survived for nearly three days with the help of his faith, his blood-stained journal, and his iPhone and (separate) camera.
He specifically credits the iPhone's alarm clock (for keeping him from falling asleep while in shock) and an app that has been identifiedas Pocket First Aid and CPR, by Jive Media LLC.
The article seems to indicate that he already had the app before the earthquake rather than downloading it from beneath the rubble, so think ahead, folks! Presumably he also had a backup battery to keep his iPhone alive for 65 hours of 20-minute alarms.
