iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple Placing Unprecedented Amount of iPhone 6 Orders, First Batch Estimated at 68 Million Units
The paper also states that Apple's first iPhone 6 order will consist of 68 million units, with the device finally entering mass production later this month. This is consistent with earlier rumors about the mass production of the 4.7-inch device, although it is unknown if this newest report is referring to joint production of the 4.7-inch and larger 5.5-inch iPhone 6.
Apple is likely pushing for a large initial order of the iPhone 6 in order to avoid the supply issues that surrounded the launches of the iPhone 5s and iPhone 5. While some reports have suggested that Apple may launch the 5.5-inch version of the iPhone 6 after the 4.7-inch version due to issues with display technology and battery life, a recent report from Bloomberg suggested that both devices could launch simultaneously.
In addition to a larger display, both versions of the iPhone 6 will most likely feature a thinner, curved-edge casing along with a faster A8 processor and improved camera. Following the trends of the past two iPhone launches, it is also likely that Apple will reveal and launch the iPhone 6 in September.
