Ok, so I have recently tried to install a game rom pack from a cydia source, but it crashed in the middle of it. So I went back to cydia, and it started crashing. So I removed cydia via mobile terminal. But when I went to reinstall cydia, it game me this message: E: Could not perform immediate configuration on 'essential' .Please see man 5 apt.conf under APT::Immediate-Configure for details. (2) I've looked all over the internet and have found nothing. I used redsn0w 0.94 and I used a custom boot screen and I have a jailbroken iPod Touch 2G (firmware 3.1.3). Could someone please tell me what I need to do? Thanks.
