Remember that tall, mostly aluminum 2012 iPhone shell that appeared to have leaked? It's back. This time, KitGuru has unearthed what it claims is a "test sample" with the glass front panel roughly intact. We've seen the darker steel sides, aluminum back and new dock connector before, but the front gives us a much better sense of how the finished product (if real) will turn out. Sitting next to an iPhone 4S, it's suggested that the new model would stuff in that bigger screen more through a better use of the available area -- there's much less blank space than on the iPhones we've known since 2007. While we still don't know for sure if the design shown here is close to what will go hand-in-hand with iOS 6 in the fall, we're starting to see enough smoke that there's bound to be a fire nearby.
