Unless you would classify yourself as an advanced user, select “User.” This ensures that Cydia will only display basic apps. When you open up Cydia, you will be asked to identify what kind of user you are. When this is done, Cydia will quit automatically and restart your springboard.
Your new app store will instead display a gray screen with a loading wheel stating “Initializing Filesystem.” Please wait while Cydia completes this process. The first time you launch Cydia, you won’t be able to access the complete app.
