Just updated from my 4.1 jailbreak to the 4.2 jailbreak with green poison. I did so by updating to 4.2, restoring from backup, performed the jailbreak, then restored with pkgbackup. Everything seemed to go fine, however, now when i try to install a new app or update apps via the app store, app store exits and has the "waiting" text and loading bar on the apps being added/updated, however, this only lasts for a couple seconds and then the app just disappears (if it is a new app im trying to install) or just returns to normal (if it is an app im updating). Is anyone else having this problem? Am i going to need to just re-jailbreak?
