I can understand the need to re-design something in attempts to get exposure, I think someone attempted a Facebook redesign relatively recently on Behance and they got a ton of exposure from that, but this iPhone concept is completely impractical, starting with that screen curving over the borders (fragile, slippery, higher costs etc). I pretty much agree, if he was so committed to the idea of a 'better' iPhone, a little more research into industrial design wouldn't have hurt.
