iPhone 4 the is the world's thinnest smartphone. iPhone 4 is about 9.3 millimeters thin. All the breakthrough technology in iPhone 4 is situated between two glossy panels of aluminosilicate glass. This is the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever.
