I have the new version 4.2.1 or I think 4.2.1b something like that, but after the most recent updates everytime I go into Cydia it closes out. I am not totlly sure why however I was thinking of ditching my JB 4.1 on greenp0ison and going back to stock. Is there anything earth shattering in the 4.3 release? I know what's in 4.2 but since Cydia's update my phone overall is acting funny Apps open then close, I shut them all down, reboot the phone and they are ok for a little while, but this is getting annoying. Just trying to see if anyone else is having a similar issue.
