This week the bootloader source code for iOS seems to have leaked in its entirety. Apple would appear to have sent a DCMA takedown notice to Github, where the code was leaked, this indicating the code posted was of some large consequence. This is a big deal because it will likely lead to custom software for the latest iPhone devices. This is also a big deal because it could potentially lead to some nefarious parties finding their way in to Apple devices with a bit of reverse engineering - but don't worry. Apple's aware of what's up.
