A highly-anticipated update to MobileSubstrate arrived this morning in the form of Cydia Substrate for iOS 7. Jay Freeman (saurik) worked quickly on the updated framework, which brings Substrate support to iOS 7 and A7-based devices with ARM64 architecture. Cydia developers will now be able to recompile their jailbreak tweaks to be compatible with the iPhone 5s and new iPads.
Moreover, the updated version of MobileSubstrate should alleviate issues that users have been experiencing with tweaks uninstalling themselves or not working properly on pre-A7 devices. It will still take a while for most developers to recompile their iOS extensions to work with ARM64, but at least the availability of an up-to-date Cydia Substrate makes the process possible.
Which tweaks will you be installing?
