The iPhone OS 1 Project

A project centered around jailbreaking iPhone OS 1. Not affiliated with Apple.

README.md

iPhone OS 1 was never meant for third-party developers, with no SDK and no App Store. This project changes that.

This project centers around development for iPhone OS 1.0-1.1.5. With a variety of modern-day tools, building for iPhone OS 1 is now possible! :)

This project is not affiliated with Apple in any way.
