More stylish than its same-named iPhone predecessor, Marware's new C.E.O. Premiere for iPhone 3G ($35) is a leather sunglass-style holster for the iPhone 3G, using a microsuede interior and a non-detachable belt clip to hold the device at waist level. C.E.O. Premiere is designed to provide access to the headphone port while inside, so that you can listen to music or take calls with the iPhone 3G's headset while you're walking.
