Famed Apple leaker Sonny Dickson
has shared an early prototype of the original iPhone
, with a collection of images and a video that provides a glimpse into one version of the iPhone that Apple created and tested before ending up with the first iteration of the device. Mac Rumors reports: The prototype includes some similar features to the first generation iPhone, like an aluminum chassis, multi-touch compatible screen, 2G connectivity and Wi-Fi, but its entire user interface is taken directly from the click wheel system of Apple's original iPod line. Called "Acorn OS," the prototype software includes an on-screen click wheel on the bottom half of the screen and a menu system on the top half, and the two are bisected by a bar with rewind, menu, play/pause, and fast-forward buttons. On the menu are options such as "Favorites," "SMS," "Music," "Settings," and "Recents," 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. Dickson references Apple's patent for a "multi-functional hand-held device," filed and published in 2006, as proof that such a prototype did exist at one point and could potentially have been an alternate version of the iPhone. In one of the patent's drawings, a click wheel can be seen as a possible input method for the proposed device. The patent's abstract describes a product with "at most only a few physical buttons, keys, or switches so that its display size can be substantially increased."
