After last week's unveiling of iOS 7, rumors about the next iPhone have started to really heat up. A photo has leaked from a Japanese electronics site today, and it's supposedly the logic board slated for use in the next iPhone. Unsurprisingly, it looks a lot like the internals of the iPhone 5 with merely a few minor differences. Simply put, this adds credence to the idea that the next iPhone won't be a complete redesign.
