More than 5 years have passed since the presentation of the iPhone 2G, 5 more iPhone models have been presented since then, and the people from iMore made a brief comparison between their designs. In total, Apple designed only 4 different designs for its terminals, the iPhone 5 being the most recent of them, but it is similar to that of the iPhone 4 and iPhone 4S. The charging/synchronization solutions for iDevices did not change as easily because Apple kept the USB cable intact until the iPhone 5 hit the market and had to be redone. Below are the pictures of the terminals and I'm curious which of the designs you liked more.
