It's been a while since we saw a really nice concept for a next generation iPhone.

Isamu Sanada created a new concept for the iPhone 4G. It has edge-to-edge glass and a contrasting brushed aluminum body. The look is definitely borrowed form the new line of iMacs.

We personally love the design and wouldn't mind going back to more noble materials like the ones the 2G used to have. What do you think?
