iPhone5 was released in San Francisco, USA. Compared with the previous iPhone4S, the iPhone5 has a lighter and thinner body, uses a faster processor, and supports 4G LTE networks. The big difference from previous products is that the size of the display has increased to 4 inches, the resolution of 1136×640 still maintains the "retina" level, and the nano SIM card is used. In addition, the data interface is also different from that of the iPhone4S.
