In a YouTube video, DongleBookPro showcases a unique iPhone 4.
This is quite an early prototype of the smartphone, featuring a Death Star logo. Physically, there are several noticeable differences: no screws at the bottom of the smartphone (they’re located in the SIM tray), unmarked volume buttons, no camera ring, a red tint for the front-facing camera.
But the most significant difference compared to the classic model is its screen: it is not Retina. It also features an older test version of iOS 4.
Finally, Apple had also planned a plastic case in the prototype’s colors.
