The code that runs on the iPhone and iPad before iOS starts, and which is commonly referred to as iBoot, was posted online earlier this week for anyone to explore it. That source code represents one of the iPhone’s many secrets, something that Apple doesn’t share with others.
A few hours after security experts speculated the iBoot code that leaked is actually a few years old, coming from iOS 9, Apple confirmed the leak is genuine. And while the iPhone maker downplayed the importance of keeping this particular type of program secret, it still forced Github to remove it.
