iPhone OS 1.0 Acorn builds are early, unleaked prototype builds of iPhone OS 1.0, dubbed as such because of the acorn found on the boot screen. Photos of these prototypes were shared by Sonny Dickson in January 2017.[1] They are currently the earliest known builds of iPhone OS 1.0.
Prototypes[edit | edit source]
The "classic" prototype was designed by Tony Fadell, and the "system" prototype was designed by Scott Forstall.
Classic[edit | edit source]
The first prototype began development in 2005. Then-CEO Steve Jobs pitted executives Tony Fadell, then head of the iPod division, and Scott Forstall to make operating system prototypes for the upcoming iPhone. Forstall won with his paired down version of OS X with a multi-touch interface, so Fadell took one of his iPods and created a prototype OS around it.
It includes a set of virtual buttons and a click wheel, with a few additions such as a call menu and a diagnostics menu, which includes features such as Bluetooth testing and CPU clocking.[2][3]
System[edit | edit source]
The second prototype introduces a touch-based interface with a bunch of crude blue boxy buttons on a white background, somewhat similar in design to SkankPhone. Likewise, it displays developer in-jokes on the bottom similar to those found in SkankPhone.[4]
According to Bob Burrough, his team designed this prototype.
