Early iPhone prototype had an iPod-like interface and a digital click wheel

A video and a series of photos, posted by Apple blogger and tipster, Sonny Dickson provides a glimpse of one of the prototypes that Apple had discarded before its first iPhone went into production.

The experimental prototype was designed around an operating system called “Acorn OS”, which was the internal code name for the software and the device shows an acorn on the boot screen instead of an Apple logo.

“Apple clearly made the right choice,” pointed out Dickson when Apple chose to ditch those efforts and focus on developing the iPhone OS that eventually became what we know today as iOS.

Acorn OS, featured an iPod Classic-like interface with a digital click wheel that could be used for navigating between menus. The screen of the prototype is split into two halves, with the bottom occupied by a software click wheel and the top by a menu-based UI (user interface) that’s a straight copy of the iPod’s.

“Much like the first production iPhone, the prototype features numerous same features including an aluminium chassis, multi-touch compatible screen, 2G connectivity and Wi-Fi radios”, Dickson writes. On the menu are options such as “Favorites”, “Contacts”, “Dial”, “SMS”, “Music”, “Settings”, “Recents” and many other, and it’s navigated by circling around the click wheel to go up and down, with a center press confirming an action, just like on the iPod.
