Well, it's silly to pay for a second phone in a first aid kit, but the iPhone can help in an emergency. An American documentary filmmaker that was trapped in rubble after the earthquake in Haiti used his digital SLR and an iPhone App to find a safe place to dwell and treat his injuries.
After being crushed under the rubble of the Hotel Montana in Haiti last week after the 7.0-magnitude earthquake struck, filmmaker Dan Woolley owes his life to his tech.
First, he used the flash on his digital SLR to illuminate his surroundings and, eventually, find an elevator shaft to rest inside. Then, he used the knowledge contained in the first-aid app Pocket First Aid and CPR to create a bandage and tourniquet to stop the bleeding from his leg and head.
The app also warned him that he may be suffering from shock and to try and stay awake, so Woolley set his iPhone's alarm to go off every 20 minutes to keep him from snoozing.
Almost three days later, he was saved by a rescue team.
We can learn something from this tragedy about our tech. When something goes wrong around the house and help is far away, your smartphone can be your life line. Armed with an internet connection and a host of applications (Is there an app for that?), you've got the world and all of it's diverse knowledge at your fingertips. Use it!
