As one of several new Marware cases for the iPhone 3G, the C.E.O. Sleeve ($25) is an improved successor to the same-named leather case released for the original iPhone. Featuring newer, cooler styling reminiscent of the Incase designs for the prior iPhone, C.E.O. Sleeve includes a detachable Multidapt belt clip, and can be used to hold the iPhone 3G in a pocket, bag, or on your belt, depending on your preference.
