UnFolder is a useful tweak for those of you who like to arrange and rearrange your Springboard folders. This tweak allows you to delete folders without having to take every single app out of them. Normally you would have to drag every app that you've put in there to your Springboard, the folder would close, you would have to reopen it, and start the whole process over. With UnFolder you can simply delete the folder, as you would with any application, and your apps will scatter, automatically, to your Springboard. You may now press the "That was easy!" button. UnFolder is free in the Cydia Store.
