Jailbroke my iphone 4 (vzw) last night via redsnow. Had no issues with the install, but after I installed a few things from Cydia I am not able to open the App Store and Safari (as soon as I click them, they load up for like 2 seconds then go right back to the main screen) I have restarted/resprung/hard power off but still nothing.
Having the same issue, I am going to try to run Redsn0w on top of my current JB to see if it will sort the issue out, but if not I wouldn't consider this a "truely untethered" JB. I also realize its been a little over 24 hours, and the Dev team is probably doing there best to sort the issues out.
Neither can I. BigBoss isn't working and 90% of my jailbreak apps are from BigBoss. Very frustrating. I wish I had waited!
I had issues with BigBoss until I went into Manage>>Sources>> and selected Edit, and deleted BigBoss...then, on the main screen, tapped 'more package sources' and Near the top, BigBoss was listed... taped that, and it downloaded the repo contents into Cydia.
