Let me be clear, these pics from giga.de that Macrumors linked to are only mock-ups. I want to be very clear.
Still, they look nice and could give us an indication of where the next iPhone's design may be headed. You might say to youself, "I've seen this before". Probably. It looks a lot like the iPod touch except thicker.
Notice it's only the same size as the other iPhones. Perhaps they don't believe that a bigger screen is in the works.
It's something to look at. I hae to say that I rather like the box. Smaller and saves more space than the current box the iPhone 4 comes in.
