P-Per Mobile Challenges Iphone - Poboo.com

This conceptual phone will advocate environmental protection and high technology. The design includes only four layers: the printed circuit board, extruded polycarbonate, recycled titanium, and a flexible tactile-dominated touchscreen. By using the least amount of material in the design, it provides the highest level of technology.

If that's not challenging enough for the iPhone, it also features a wafer-thin form factor of about 7 mm, a 3-megapixel camera, and a 2-minute charging interval!
