This huge early iPhone prototype had a 5-by-7 inch screen and a plethora of ports

Early iPhone prototype

A 2005-era iPhone prototype revelation is a good reminder of how far we’ve come in the mobile world.

The above iPhone prototype sports a massive 5 inch-by-7 inch screen and is about 2 inches thick, reports Ars Technica. It also sports a plethora of ports, including Ethernet, USB, and serial port — which makes us think it’s more of a development kit for Apple’s engineers.

The large size puts it far closer to the iPad’s design — especially the 7.9-inch iPad Mini.

The images come from an anonymous Apple staffer who worked on the company’s hardware projects in the early 2000s. It may be hard to see how this monstrosity would eventually turn into the first iPhone, but a source tells Ars that the Samsung ARM chip and logic board shows that Apple had a decent idea of how the iPhone would end up.

The huge screen size and width may sound extreme by today’s standards, but it was still pretty impressive for something from early 2005. Apple also never intended to make all of the ports available in the iPhone — they were just there to make it easy to work on, a source tells Ars.

The road to the iPhone’s debut in 2007 was a long and difficult one for Apple, as we’ve seen from the plethora of prototype images unearthed from the Apple v. Samsung trial. And while Apple managed to squeeze down the original iPhone’s hardware into a device with a 3.5-inch screen, it’s funny that we’re now seeing huge phones like the Galaxy Note line.
