Early iPhone prototype with 5'x7' display

Most leaked iPhone prototypes have been run-of-the-mill devices that resemble the iPhone we know and love. This latest leak from Ars Technica reveals the tablet roots of our favorite smartphone.

These prototype images originated from 2005 and show an iPhone with a 5 x 7-inch display and a variety of tacked-on ports that were used in testing. As you can see in the image above, it's a Frankenstein-like device that looks more like an iPad than an iPhone.
