Richard Ryan (iPhone shooter extraordinaire) gives it a shot:
¥52,500 ($672 USD) for the super practical bulletproof case. I’m not surprised the bullet didn’t penetrate the case, nor am I surprised the phone wouldn’t power up. That is a heck of a lot of energy transferred to the phone which it obviously wasn’t designed to take.
A bit of a flawed test though considering it’s unknown whether the round caused the phone not to function or it it was from when it flew and hit the rocks. Fun though, either way.
