LifeProof iPhone case

£49.53
LifeProof
A hard-as-nails case for the iPhone 4 and 4S that manages to add a mere 1.5mm to the edge and 28g to the weight, this offers military grade protection against droppage (it’ll withstand a 2m fall), plus sealing to keep out water (to 2m) and dust. If you’re jogging or taking part in something equally active and can’t leave your phone behind, clothe it in this.
