Apple can't keep a lid on the latest case designs according to Mobile Fun, who claims to have two independent sources with iPhone 5 case plans. If the leaked designs are legit, it would appear the iPhone 5 is due for release in just weeks. Of course, the cases themselves are not as important as the future devices they will protect.
As seen above, the design of the iPhone 5 will not be simply an update of the iPhone 4 that some are calling the iPhone 4S. What appears in these diagrams is a radical departure not only from the iPhone 4, but possibly the most significant redesign of the iPhone since its original 2007 launch.
