Here's how iOS 8 could look like on the 4.7" display of an iPhone 6 (video)19
A 4.7" iPhone 6 is expected to go official in August, and shortly afterwards, a 5.5" Apple phablet is said to be in the cards. The new iPhone 6 will allegedly have a screen with a resolution of 960x1704 pixels, which is much higher than the current 1136 x 640 pixels on the iPhone 5s, but the screen is quite larger, too. Apple might be going for tripling the original iPhone resolution, but preserving the 16:9 aspect ratio that came with the iPhone 5. This triple scaling should allow an easier transition for developers, making it easier for them to update their applications.
The sources who disclosed this new iPhone resolution, also said that the iOS 8 interface will likely just be expanded to fit the larger display, while only a few native apps, like Apple Maps and Safari, will be scaled to make a better use of the new pixel density. If so, the folks from 9to5 Mac took the 4.7" display of the Moto X, and wrapped the leaked iPhone 6 dummy chassis around it, showcasing how iOS would likely be stretched to fit a 4.7-incher.
