Okay so I just removed cydia using mobile terminal, and now cydia is gone from the springboard, but when I try to reinstall it via mobile terminal, it gives me the error ": Could not perform immediate configuration on 'essential'.Please see man 5 apt.conf under APT::Immediate-Configure for details. (2) " This is after I type in "y" when they ask if I want to continue. This is frustrating me so much!! Please help!!
