Video: This is what happens when you shoot a ‘bulletproof’ iPhone Earlier This week we wrote about the Holy Grail, a new smartphone screen protector that maker Sir Lancelot's Armor touted as being made from "bulletproof" glass. Yes, there was a reason that we put the words "bulletproof" in scare quotes: While such glass may indeed be the same type of glass used in bulletproof *******, it probably wasn't strong e**ugh to stop an actual bullet from doing serious damage to your iPhone. And sure e**ugh, Ars Technica has decided to do yeoman's work by actually firing a gun at a Holy Grail-equipped iPhone... and the results were **t pretty.
