Rumors from sources that are supposed to know about the issue want Apple to try to build the upcoming iPhone 6 with a thickness that will not exceed 6mm.
According to the Chinese website ET News:
"Apple's upcoming iPhone is already known to be in development and is expected to be released this year. It will be very thin, while the weight of the metal frame is expected to increase slightly. "
The site reports that the thickness of the device will be 6 millimeters, which is pretty thin even for Apple's standards. According to the same sources, Apple wants to achieve half the thickness of the iPhone 3GS, which was 12mm thick.
The frame will continue to be made of metal, and there will be two models. One by one screen 4,7 inches and the other with a screen that will be almost six inches – in fact we will see the first phablet from Apple.
