iPhone OS 1.0 Acorn builds or AcornOS are early prototype builds of iPhone OS 1.0. It was named after the boot screen of the 2 known prototypes.

The 2 prototypes were both unleaked, shown by Sonny Dickson on January 2017. The builds run on P1 and P2 iPhone prototypes respectively. [1]

Prototypes[edit | edit source]

According to rumors, the P1 OS was designed by Tony Fadell, and the P2 OS was designed by Scott Forsal.

P1 prototype (Classic)[edit | edit source]

The P1 classic prototype started developing in 2005, by then CEO Steve Jobs, and he pitted executives Tony Fadell, who was head of the iPod division and Scott Forstall to make operating systems for the upcoming phones. Forstall won with his paired down version of OS X with a multi-touch interface, but Fadell took the iPod and created a prototype OS around it.

It is based on OS X[2], with a virtual set of buttons and a click wheel, and the system has a few additions such as a call menu and a diagnostics menu with stuff such as bluetooth testing and CPU clocking.[3][4]

P2 prototype (System)[edit | edit source]

The P2 system prototype has a touch based interface with a bunch of crude blue boxy buttons on a white background. It had developer jokes on the bottom similar to how SkankPhone has them.[5] Due to it's similar layout, this prototype’s GUI might have evolved to SkankPhone.

According to Bob Burrough in a YouTube comment, his team designed the prototype, and he claimed iPhone OS was so secret that only the people which got approved by Steve Jobs can see it.
