Of course I heard of Jailbreaking. The difference was that jailbreaking and modding consoles requires modified hardware to run unapproved software (digitally distributed). But reverse engineering the development tools and the signing keys in order to create unapproved disks or cartridges is a viable method to create software for unmodified devices. See FreeDVDBoot for the PS2.

Jailbreaking definitely does not require modified hardware. You also don't need to jailbreak to install 3rd party apps. See http://altstore.io/.

By modified hardware I mean a device that is not in its default state. Jailbraking alters the firmware making a jailbroken iPhone different from from a mint one.

I did not know about that one but I did know of AppValey and others that work based on enterprise certificates. I am not sure what prevents Epic from using this method to create an alternative store or why Apple does not claim that if you want you can have alternative stores on iOS therefore there is no antithrust issue.

Of course AppValey and the like require installing a root certificate.

Also, none of this allows you to unlock the bootloader.
