Launching with iOS 8.1.
iPhone 6 Case Maker's Model Points to Larger Display, Ultra Thin Body
The iPhone case model appears to have rounded corners and a single unified volume switch, which is different from the separate volume buttons in the iPhone 5s. It's also a slight deviation from earlier design drawings, which showed separate rectangular volume buttons, suggesting this model may come from a different source.
Though not depicted on the case model, separate rumors have pointed towards a relocated power button, either on the top left edge of the device or on the side of the device, to improve one-handed use on a larger device. Currently, the power button is located on the top right edge of the iPhone. Bezels are also not visible, but rumors have indicated they could be 10 to 20 percent thinner than the bezels of the iPhone 5s and the phone itself may be 6.5mm to 7mm thick.
Earlier this week, MacRumors published a set of renderings based on the schematics that share similarities with the case model, depicting what the finished iPhone 6 might look like.
Apple's iPhone 6 is expected to come in two different sizes: 4.7 inches and 5.5 inches. Recent rumors have indicated the 4.7 inch version will be available to ship in in the third quarter of 2014, while the larger version may ship somewhat later due to production delays.
Reliable analyst Ming-Chi Kuo has suggested the 4.7-inch iPhone will have a 1334x750 Retina display with 326 pixels per inch, while the 5.5-inch version will have a 1920x1080 screen with 401 pixels per inch.
Along with a larger screen, both versions of the iPhone 6 are expected to include an upgraded A8 processor, Touch ID, 1GB of RAM, and camera improvements in the form of optical image stabilization.
