Cydia allows for the addition of as many repositories as you want. What is a repository? It’s basically a webserver that hosts files that you can install on your iPhone. Some repositories, such as Hackulo.us, allows you to add increased functionality to your phone’s backend. Others, such as XSellize, allow you to download and try out applications before purchasing them. To add a repository in Cydia, follow these instructions:
- Open up Cydia, and tap on Manage (it will take some time to load Cydia)
- Tap on Sources
- Tap “Edit” in the top right corner, and then in the top left corner type Add
Once on this screen, type in the full URL to the repository.
Hackulo.us: http://cydia.hackulo.us
XSellize: http://xsellize.com/cydia/user-password
XSellize requires a username and password to access their repository. Simply sign up on their website and you should be able to access it.
You’re done! You just added a repository in cydia
