The SGP Linear Blitz Case for iPhone 4S and iPhone is simply beautiful and the attention to detail is exquisite. The SGP Linear Blitz Case has rounded, two metallic-looking sides. The main, top part is finished in champagne gold while the the lower portion is finished in satin sliver. The back comes in red, gunmetal gray, and black. I took a look at the red version and... my, oh my.
