My iPhone 6 mockup has a 4,56 inch Retina+ screen with the already known iPhone 5 ratio 16:9, but with a FullHD screen, with a resolution of 1920×1080 Pixel.
iOS 8 is now in the clear style of Jonathan Ive. Simple and clear, but useful. The lockscreen shows you now not just time and date, also the current weather and forecast is now constantly on your lockscreen. The whole notifications on your lockscreen now appear much clearer and more intuitive.
