The new iPhone 5, coming this fall, may not go back in time to kill John Connor, but it could be made from Liquidmetal, at least according to the latest rumors. Unlike normal metals, which are crystalline, Liquidmetal is an alloy more like metallic glass, with the elasticity of plastics but two or three times harder than titanium. All of which could make the new iPhone much thinner and more durable, reports the Telegraph. Apple signed an exclusive deal with Liquidmetal Technologies in August 2010, believed to be in the $11 million to $20 million range. However, reports caution that these are just rumors, and Apple is being as secretive as always.
