IPhone 6 [SEP] Software
When first released, the iPhone 6 and iPhone 6 Plus were supplied pre-loaded with iOS 8, while the iPhone 5S was supplied pre-loaded with iOS 7. Apps are able to take advantage of the increased screen size in the iPhone 6 and 6 Plus to display more information on-screen; for example, the Mail app uses a dual-pane layout similar to its iPad version when the device is in landscape mode on the iPhone 6 Plus. As it uses an identical aspect ratio, apps designed for the iPhone 5, iPhone 5C, and 5S can be upscaled for use on the iPhone 6 and 6 Plus.
