Back in December, we got our first proper look at iMods,
an alternative to the long-standing jailbreak portal that is Cydia, and
with its enticing, modern layout and App Store-like graphics, it has
left more than a few jailbreakers eager for the release. Now, it has
emerged that Comex, former wizkid and author of JailbreakMe, is creating
a new alternative to Cydia Substrate called Substitute from the ground
up, and notably, iMods will be using it.
Cydia Substrate, simply put, is a platform created by Saurik, author
of Cydia, WinterBoard, and many other long-standing or otherwise
integral components of the jailbreak arena. Cydia is the portal, but
Substrate is the underbelly, providing an infrastructure for developers
to create add-ons that can modify the iOS experience without access to
the source code.
