Thinner, lighter: The new phone is made entirely of glass and aluminium. Apple calls it its thinnest and lightest yet, at 7.6 millimeters (0.3 inch) thick and weighing 122 grams (4.3 ounces). It’s 18 percent thinner than the iPhone 4S and 20 percent lighter. Pictured is Apple marketing senior vice president Phil Schiller.
