The first look at the original iPhone prototype is a fascinating journey into the past and the question that Apple's research and development team needed to address in order to make the iPhone a reality. The prototype contained a multitude of features you would never expect on a smartphone, and all are shown in newly published photos.
The prototype board was reportedly used by engineers tasked with designing the original iOS software (even before it was called iOS) and testing the wireless functionality. It can be said that it is a prototype because the board itself is red – a common indicator for an Apple prototype – while commercial boards in Apple products are green or blue. The prototype consisted of parts of several companies, including a Samsung processor and memory module, as well as various chips from Intel, Infineon, CSR, Marvell and Skyworks. Overall, it is amazing to see how far the iPhone has come, not only from this prototype to the eventually delivered product, but also how far the iPhone (and the smartphones in general) have come in the 12 to 13 years Since Apple engineers it was with this prototype.
