I don't know how many people have iPhones, but I am guessing a pretty good amount. Here is a video of my cousin who is a skydiving instructor taking a 91 year old woman out for her first skydive. At about 2:42 in, you will see his iPhone go flying from his pocket at around 11k feet.
Here is the video:http://www.youtube.com/watch?v=hbquFJJg ... e=youtu.be
He called AT&T and they activated the family map to locate his phone. He took a paper copy of the map out to the woods with him two days later and actually found the phone. The screen wasn't cracked or anything. It survived an 11,000 foot fall without a scratch. Pretty cool!
Only protector he had was the Magpul iPhone Field Case:http://store.magpul.com/product/MAG451/
Not saying that it will withstand all issues, but for a $10 cover, seems like something that would be worth investing in if you are an iPhone owner.
The final weapon is the brain. All else is supplemental.
