From YankoDesign: I love me a wild iPhone concept as much as the next fanboy, but few
challenge the true, obvious setbacks of the current devices. Designer
Enrico Penello’s iPhone 4S concept tackles some of the existing flaws of
the 4th generation phone with some very simple solutions and a few
extras. The fixes: a lightly textured plastic back case for better
grip, a removable battery for easy replacement, and a fixed lower cover
for the WiFi antenna. The extras: iOs5, 8 megapixel camera, and a
faster A5 processor.
