Nonetheless, let’s get down to see some more details on the matter.

Take A Look At The Original iPhone M68 Prototype In All Of Its Glory

As can be seen in the images provided, Apple manufactured special prototype development boards. The unit features a red PCB as Apple intended it for the prototype. The production units, on the other hand, had a blue or green colored PCB. The board you see in the images was designed for the engineering validation test (EVT) sample and was used by engineers working on the modem and software of the device.
