iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Images Depict Possible iPhone 6 Lightning/Headphone Flex Cable, Rear Shell
The flex cable said to be for the iPhone 6 includes the headphone jack on the far left, a microphone next to that, and the Lightning port located on the middle of the part. It looks very similar to the Lightning/headphone flex cable designed for the iPhone 5s, but the headphone jack has dual screw holes towards the top of the part, a variation from the iPhone 5s design.
These two holes appear to accurately line up with the dual holes in the bottom left of the rear shell of the device, suggesting the headphone jack would fit correctly into the iPhone 6 rear shell and lending credence to the authenticity of the part.
As for the rear shell, it appears very similar to previously shared images of the iPhone 6 rear shell, including a near-completed rear shell with embedded Apple logo that surfaced yesterday. Like that shell, this one features an iPad-style embedded Apple logo, clear cutouts for the camera and flash, and very prominent antenna breaks.
Some reports have speculated that the embedded Apple logo is designed to light up, but it is more likely that the embedded logo is for aesthetic and/or radio transparency purposes.
As we creep closer to the prospective September launch date of the iPhone 6, part leaks may grow even more frequent. Thus far all part leaks have centered around the 4.7-inch iPhone, and this is because it is believed to be entering mass production ahead of the 5.5-inch version. The 5.5-inch iPhone 6 may enter production in August or September according to rumors, which means 5.5-inch part leaks could pick up over the next month or two as well.
