Heres a layered psd of the new Iphone 7 in jet black. There is a lot of shadows and gradients in this one, so if you plan to scale it or rotate it I would recomend using the smart object version thats also included in the psd.
Enjoy and dont be afraid to share it! I always appreciate a link back!
(I've updated it and tweaked the glass in the version 2, see the larger version to see it)
