With less than 24 hours of owning my 64GB Space Gray, I decided to see how my naked iPhone would do when dropped from chest high on to the tile floor of my house. I'm happy to report the phone handled the drop very well and only received a nasty ding and scuff on one corner. So for those of you itching to make sure the 5S holds up to a drop, I've gone ahead and blazed that trail for you.
