The administrator Winocm also known for his announcements of "upcoming" iOS 6.1.3/6.1.4 Jailbreak announced that managed to run iOS on a Nokia phone and specifically to Nokia N900.
the ambitiousjail breaker" (we hear about jailbreak but don't see it) managed to port the Darwin kernel to the ARM architecture.
The Darwin is the core operating system found in Mac OS X and iPhone OS. It is the foundational kernel that bridges the kernel with the operating system's UI. (SpringBoard/login screen etc). This practically means that iOS can run on ARM devices but there is no connection to the OS UI. So the screen of Nokia looks like a terminal window.
The operating system that runs on her Nokia photos is iOS 4.3.5. The source code for those interested is at GitHub.
