Ars Technica has just published photos of another early iPhone prototype, which looks more like iPad mini and measured 7×5 inches in size and nearly 2-inches thick.
This early iPhone prototype also included USB ports, an Ethernet port, and even a serial port, but Ars Technica’s tipster points out that those were included to make it easier to test the device.
The early prototype is also quite large—about 5″×7″ and roughly two inches thick. “Seems large now,” our source said, “but at the time it was really impressive seeing basically a version of OS X running on it. “From the looks of the logic board photos, Apple had a decent idea in 2005 of where the iPhone would end up, even if the final product became much more integrated.
The ARM chip looks like a variant of the Samsung S3C2410, which Ars Associate Writer Andrew Cunningham said is “a distant relative of the chip the first iPhone ended up using, just older and slower.”
Indeed, the chip shown above was clocked at 200-233MHz, while the first 2007 iPhone used a 620MHz chip underclocked to 412Mhz. “This chip is also an ARM9 chip, while the original iPhone eventually ended up using an ARM11 chip, but obviously Apple intended to use Samsung-manufactured ARM chips even this far back,” Cunningham said.
It’s amazing how Apple managed to turn this early prototype into iPhone that measured 4.5×2.5-inches in size and 0.46 inches (11.6 mm) in thickness (iPhone 5 is only 7.6 mm thick). We tend to give Apple all the credit for the launching the revolutionary iPhone, but when I see these early prototypes, it reminds me that Apple wouldn’t have been able to achieve it without the help of component manufactures who have been shrinking the components going into the iPhone year after year.
