The device weighs a somewhat hefty 145g and measures up at 115mm x 61mm x 12mm (4.5" x 2.4" x .47"). Into that iPod they stuffed a working version of Apple's operating system, OS X. They put in a cell antenna, plus two more antennas for WiFi and Bluetooth; plus a bunch of sensors, so the phone knows how bright its screen should be, and whether it should display vertically or horizontally, and when it should turn off the touch screen so you don't accidentally operate it with your ear.
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.
