after unistalling Corona so as to re jailbreak with redsn0w, my iphone went into a respring loop. i re jailbroke, phone booted up with all tweaks installed and everything worked just fine. but after going to Cydia, it asked to update itself, which i did. but after rebooting, none of my installed packages showed up. i found a forum saying i need to go into iFile under var>lib>dpkg and delete the "available" and "status" and then take the "old" off of the backups. i rebooted and loaded Cydia, but packages still not showing up. anybody have this problem?
