Apple collector Hap Plain can observe the iPhone’s 10th anniversary today by powering up two extremely rare iPhone prototypes — and you can see them in action, too.
The prototypes, which likely passed through the hands of Apple execs including Steve Jobs, Tony Fadell and Scott Forstall, offer a unique glimpse at iPhone development. You can see Plain fire them up in the video below, the latest entry in Cult of Mac’s collaboration with Wired UK to recap a decade of the iPhone.
