I recently jailbroke my ipod using redsn0w and have cydia and what not. The first problem im having is with packages. I'm trying to get packages by going to sections, but the only section i see is "all sections". And when i open that up there is nothing there but a blank screen. So i went to the cydia home screen and went to featured packages and clicked on a package to try and get it that way, but it came up with an error saying i need to install more sources. What does that mean and how do i do this?
