Next-generation iPhones likely to focus on internal improvements.
Possible 5.5-inch iPhone 6 Volume/Power Flex Cable and SIM Card Tray Shown in New Images
The two flex cables that separately house the left side volume buttons/mute switch and the top power button are similar in design to an earlier set of leaked flex cables said to be for one of the iPhone 6 models. There are, however, some design differences that suggest there are two distinct sets of flex cables designed for two different devices floating around the Asian supply chain. For example, the new set of flex cables depicts less space between the volume buttons and the mute buttons and the two flex cables for the power button have different shapes.
Like the earlier cables, the flex cables in the new images resemble parts from other devices and have an Apple-style part number.
As it is difficult to determine size based on images, it is unclear which set of leaked flex cables might be designed for the 4.7-inch iPhone and which is destined for the 5.5-inch iPhone, but as both cables are different than existing parts for the iPhone 5s, iPad Air, and iPad mini, they point towards two separate devices if legitimate.
Apple.club.tw has also shared images of a longer flex cable with an unknown purpose and a set of SIM card trays in a cobalt blue color. Blue is not expected to be a color for the iPhone 6, as current rumors have pointed towards a release in the existing silver, gold, and space gray for both models, so the blue SIM trays are somewhat questionable.
As we move closer to the September launch date of the iPhone 6, we expect part leaks to become more frequent. We may also see more parts designed for the larger iPhone 6 as it is expected to enter mass production in August or September. The 4.7-inch iPhone is said to have entered mass production in July.
Rumors have suggested that Apple may ship the 4.7-inch iPhone 6 ahead of the 5.5-inch iPhone 6 due to supply constraints with the latter, so it remains unclear if we will see the bigger phone at Apple's prospective iPhone 6 launch event in September.
