Photos of iPhone prototype reveals it was the size of an iPad
Images of the original prototype for the iPhone have been released online, highlighting how far Apple's mobile phones have come since the first iteration was sold in 2007.
The photos were shown on Arstechnica.com and revealed a device which is the opposite of today's slim and sleek smartphone.
The prototype was two-inches thick, with a screen measuring five-by-seven inches.
An image of the bottom of the iPhone revealed a number of different ports, including USB, Ethernet and serial, which are more commonly found on desktop PCs.
Speaking to Arstechnica, the source who revealed the photos said that the prototype "seems large now, but at the time it was really impressive seeing basically a version of OS X running on it".
The ARM chip used in the prototype appears to be a variant of the Samsung S3C2410, and Apple has continued to use processors manufactured by its rival in its newest iPhone versions.
