by looking at codename (N56) I think 5.5" iPhone 6 will be with the specs of last year model iPhone 5 (N51). Am afraid it will be just increase in screen Size, like they did with iPad mini when they cud have put retina display.
5.5" iPhone 6 looks like HTC Desire 816 but 3X the cost!
For the first time ever, the iPhone 6 will be taller, wider, and heavier than before lol
This is a prototype or fake that has been rumoured in February this year. Even the date appear on the bottom left corner
