Not to be used as a weapon, this knuckle-busting case gives you an iron-clad grip on your iPhone 4/4S. Machined from solid aluminium, you can thread your knuckles through the loopholes and carry your handset around like an extra mitt. But be warned – our publisher’s review sample was seized by the Australian Customs Service.
