A chrome frame surrounds the glass that covers the black face of the iPhone. A matte finish metal covers up most of the sides and back of the phone where, oddly, the phone's serial number and IMEI are clearly written. The camera lens, also located on the back, is very small and unobtrusive.
One of the only places where plastic is used on the device, and the only place it is used as a cover material, is along the bottom section of the rear of the device where the speaker, microphone, and standard 30-pin iPod docking port are found. Plastic was needed here so as to not obstruct the phone's antenna. Plastic is also used, sparingly, for the remaining few controls on the iPhone. The ringer switch and volume controls, which are found on the left edge of the device, are made of plastic. A well hidden SIM card slot is located on the top of the device, sitting between the plastic standby/power key and the 3.5mm headset/headphone jack.
I find few things to fault with the iPhone's physical design, but the headset jack is one of them. It is deeply recessed and will force many owners to purchase an adapter to use their own headphones. Another problem is the rear cover of the iPhone: it cannot be removed. Accordingly, the user cannot swap the battery. When the battery starts to lose capacity after 300 to 400 charges (according to Apple), the iPhone will have to be sent in to Apple to receive a new battery, a process that takes 3 business days and will cost US$86, including shipping. I am happy to report, however, that my initial concerns about the durability of the iPhone's finish seem unfounded. The iPhone ships with a dock, a stereo headset with a call button, and a cable that can attach the iPhone to either a computer or the charger.
