We don’t cover iPhone cases very often, and that’s because they’re usually not that cool. But I think this case is definitely the exception to the rule. The iPhone 4 case is called the fireTI and is made from 6AL-4V aerospace grade titanium.
Although I don’t think it will help very much in shock-proofing your mobile phone, say if it happens to fall 4-5 feet. I think the main reason why anyone would wanna spend $225 on an iPhone case is because it looks damn cool, and everytime you have to take a call, you’d be using a friggen titanium case.
