The fourth generation iPhone parts were apparently bought by one of their readers in China.
iPhone Portugal claims:
These parts were purchased in China by one of our readers (weren't stolen or found) then delivered to us. We will not reveal the price. Are those parts genuine? We can not know but we can tell for sure those parts are perfect, have no defects, not faulty at all, there is not even one single difference between the 2 copies we have.
There is no way to confirm the authenticity of the parts but they’ve shot a video to show the high quality of the parts:
We can’t wait to find out if the lost next generation iPhone will be unveiled as the fourth generation iPhone or if Apple will surprise us with a completely different and hopefully even better looking next generation iPhone.
