After releasing his Sn0wBreeze jailbreak for iOS 4.1, iH8Sn0w has decided to follow the steps of Chronic DevTeam and their GreenPois0n jailbreak by making SnowBreeze’s source code open source.
That means that anyone can download the source code to tweak it and hopefully make it better. I think this is particularly good for wannabe iPhone hackers. Downloading the source code will help you see how a jailbreak works behind the scene.
You can download SnowBreeze’s source code from Github.
