I added the Xbmc source, http://mirrors.xbmc.org/apt/ios/, and started installing XBMC but the download was taking a really long time so I closed Cydia and planned to install it later. Now all my sources are gone and it says I have 0 packages installed. And it won't let me add any sources. I've tried a respring and reboot but no luck. I'm not even sure if the XBMC installation attempt was even related but it's seem kind of a coincidence. Anyone have a similiar problem and/or a solution? [update] Looks like XBMC being partially installed caused the problem and Cydia eventually detected the issue and helped me remove it. All fixed!
