Handsets jailbroken with Pwn20wnd’s unc0ver tool will have Cydia installed as the default package manager, and with a newly-released free jailbreak tweak dubbed addsource by iOS developers yuosaf01 and 3bod_syr, you can augment the app’s native repository-adding functionality.
With any typical Cydia installation, users will need to enter a repository’s URL manually by tapping on the ‘Add’ button in the app’s Sources tab. This method works, but it tends to be cumbersome and exposes users to an increased likelihood of human error while typing the designated repository URL.
