Sonny Dickson -- who made a name for himself last year by leaking accurate details on the iPhone 5S prior to its arrival -- tweeted over the weekend an image of what he claims is a design improvement to the Lightning cable that will connect to the long-rumored iPhone 6. While the already-reversible eight-pin dock won't change, according to Dickson, the other end, where users plug the cable into a USB port, will now be reversible as well.
