I've checked all (5) of my iPhones on my Family Plan and to my amazement, "0" cracks. Thankfully, we all have cases and I know of only one drop so far, that occurred just yesterday. I took my iPhone off my belt and it slipped out of my hand as I was unplugging the headset and it fell slow motion, bounced off my knee and flipped end-over-end about four times, then landed on the carpet and rebounded about 6" and I caught it before it bounced on the hardwood floor. 😱 A cursory search revealed no damage to my iPhone, but my dang Griffin Elan Leather Clip snapped into two pieces and that's the reason it slipped from my hand. All I had in my hand was the broken half of the clip and my Bose headphones in the other, and just moments ago I was walking from my driveway made of concrete and brick...😱
