Sonny Dickson released a series of footage and images showcasing an early wheel-based prototype of the original iPhone that eventually lost out to the beloved iOS interface we’ve all come to associate the handset with these days.
Both versions ran an experimental OS with the codename ‘Acorn OS,’ the wheel-based interface offered faster performance since it used a lightweight version of the operating system. Still, the icon-based approached proved to be the more compelling variant.
When the iPhone was undergoing development, both projects ran what is know as Acorn OS and ran on the same hardware. Both teams were extremely competitive because both project teams wanted to impress Steve Jobs.
The P2 loads octopus whereas the P1 has the iPod classic logo. The P2 takes a significantly longer to load because it actually has a real OS, whereas the P1 takes much less time since the OS is slimmer.
