I finally decided to upgrade to 4.2.1 and use redsn0w to jailbreak. I used the guide from redmondpie and used "redsn0w_win_0.9.6rc8" for the jailbreak. Im jailbroke and was able to restore my packages from PkgBackup. My packages seem to work besides "Rename" and "Booky Folders", If you have a way to fix those let me know but for now I figure they just are not compatible.. My problem is I can open Cydia and look at Cydia, Sections, and Search tabs. and most of the manage tab. But if I scroll past the first group of packages in the Changes tab, Cydia closes and I'm back to the home screen. Same thing if I look at Manage>Packages. I tried 2 reboots (into jailbroken state) but was hoping not to have to Install Cydia again. If I Must install cydia again, will that mean I have to use PkgBackup and restore again? Any help is greatly appreciated.
