Iphone 5 feature

The iPhone 5 will keep a relatively similar size and shape as the iPhone 4 but Apple has decided to move away from the back-glass enclosure found on the fourth-generation device and move to something similar to the back of the first-generation iPhone from 2007. Although some reports claim the iPhone 5 will adopt a curved metal back, our source says models have been floating around with a flat metal back. The material of this metal is unspecified. Our brains say aluminum but our hearts wonder if this could be Liquid Metal.
