tJust attempted my first jailbreak with Greenpois0n. It appears to have worked - I see the skull on loadup, Cydia installed (I try to re-install via the Loader and it tells me it's already installed)...but Cydia won't open. The screen flashes, and then it goes back to the main screen. I've rerun the jailbreak and rebooted, but Cydia still won't open up. I'm about to just restore my backup, but I really want to make this work. Help?!?!?!?
