9to5mac, one of the most reputable when it comes to Apple Rumors, posted what they claim to be leaked iPhone 5 enclosures.   Notice that in these pictures you can see the smaller dock connector as well as a relocated headphone jack.  I do not know how I feel about the metal back.  Sacrificing beauty for durability, tisk tisk.

Check back for more updates and rumors as they trickle in.
