The iPhone 4 is one of the greatest personal media devices ever created. Except of course when it’s being deathgripped. Or when it’s broken because you dropped it and it’s more than 50% glass. Or when it’s dead because you used it for more than five minutes. In order to fix all the problems with the iPhone 4 you’re going to need some magical, mythical device capable of doing everything short of curing cancer. Or the Mophine iPhone 4 Juice Pack Air. The Mophine Juice Pack Air provides full protection (what man doesn’t love that?), doubles the battery life of the iPhone 4, and also prevents the deadly deathgrip. The slim profile makes sure the only thing taken away from the aesthetic is the glass. The LED status indicator makes sure you’ll always know how much time you have left to tweet – or lay down towers.
