If you’re the kind of person who takes their iPhone into a firefight, then you know that the usual flimsy cases won’t do much, especially against larger caliber guns. Check out Marudai’s bulletproof iPhone case. They claim that it will stop a .50 caliber bullet. Tough enough for you?
I suppose if you’re in a war zone, this could come in handy. The case isn’t very sexy, and the back is a bit thick, but I guess that thickness is needed to stop a machine gun from going to town on your iPhone. I’m sure that soldiers and mercenaries who carry smartphones will appreciate this.
If you want one, you’ll need to order it through Marudai’s site[JP] and you’ll have to pay ¥52,500 (~$650 USD) for it. It’s certainly not cheap, but then again if it keeps your lines of communication open when you’re under fire, it’s well worth it.
