iPhone Prototype Looked Radically Different March 12, 2013 - 9:37AM 227 reading now Oversize: The iPhone prototype. Photo: Ars Technica This post was originally published on Mashable. The iPhone may be sleek and light in the hands, but according to newly surfaced photos it once looked quite different to how we know it today. While it was undergoing development, the iPhone was much larger and even had Ethernet and USB ports. Tech site Ars Technica has obtained pictures from a former Apple staff member of what it is calling "a super-early iPhone prototype," circa 2005. These pictures offer a fascinating look at how the device looked while it was still being tested. What's most striking about the pictures is the device's size. The concept measures in at 5 inches by 7 inches, the report says, and is much more in line with the iPad mini (5.3 inches by 7.87 inches). It's also much thicker at 2 inches. Besides it being much bigger than what we're used to now, it also has many features included on standard PCs, such as USB ports, an Ethernet port and a serial port. However, it's important to note that Apple wasn't planning on releasing the device as shown in the pictures - some features were included to make the development process easier. But a source told the publication "at that early date no one knew what [the final device] would be."
