Can it be iPhone 7?
There are a lot of leaks about iPhone 7 indicating iPhone 6 / 6S-like design but with a redesigned antenna lines.
Steve Hemmerstoffer just published two photos of alleged iPhone 7. The design of the phone is congruent with the previous leaks and renders, but still there is a high possibility for the phone to be fake. Anyway, it is in gold color, although it says Rose Gold in its box. And yes, the leaks also includes its box.
Honestly, I do not trust to this leak but still there is a chance for the leak to be true ( also there is a high chance for the phone to be fake. )
