Apple to release iPhone 7s, iPhone 7s Plus, and a special model codenamed Ferrari in 201726
Supply chain sources also claim that this iPhone's internal logic board will be spread in two halves, connected with a ribbon cable. Board nr. 1 will feature the essential hardware, such as the A11 chipset and NAND flash storage, while the second board will house the cellular components. Additionally, the SIM card tray will be relocated towards the bottom of the handset as to free more room for other internal components. This is an idea borrowed from the iPad Pro.
This isn't the first time we've heard of rumors like these, so there are pretty good chances about their credibility. The months ahead are bound to tell us even more details about them.
