I did use greenpoison. It was successful, and the 3 pages went away after connecting to Itunes. The loader is probably a broken game, as the game's icon is gone and "loader" is in its place.
...Not quite sure why you're getting this "Loader" instead of Cydia. greenpois0n, by default, installs Cydia on your device upon jailbreaking. But hey, if it's working for you, it doesn't really matter.
Even though Cydia is better.
