comex, for those of you who don't know this yet, is one of the most famous developers of jailbreak for iDevices, he created some of the solutions launched until the appearance iOS 5. Seeing how much potential the young man has, the company Apple Lossless Audio CODEC (ALAC), offered him a job, which he accepted, but left in the end without giving any clear explanation. From then until now, comex has been working on an alternative for Mobile Substrate, the most used plugin for modifying iOS functionality.
Mobile Substrate was developed by the creator Cydia, saurik, and comex develop a substitute called Substitute with the idea of giving us a much better experience for using iDevices. Realization Substitute it is made in collaboration with the developers imods, a team that has been creating an alternative for the application for some time Cydia, as it is still far from completion. Now if you wonder why comex initiated this project, well, he wants a software that affects the iOS operating system as little as possible, but which is open and can be easily verified by anyone.
The way I see it, jailbreaking is fundamentally about taking something closed and fixed and opening it up to hacking and modification: perhaps allowing a mess to be made, but quite possibly ending up with something unique and different. This ideal of openness is very similar to that of free software, and I therefore believe that it's in the spirit of jailbreaking to make as much low-level stuff open as possible, both for inspection and modification by curious users.
Basically now comex says that the Mobile Substrate is closed and does not allow modification or verification, so he wants something better and easier to administer, so Substitute will be released sometime in the near future.
