So I jailbroke my iPhone 4 iOS 6 with redsn0w like a week ago and everything was fine until I downloaded the Zeppelin tweak (lets you change carrier icon) and my iPhone was stuck on the apple screen. I left it alone until the battery died and then rebooted it. I have a tethered jailbreak so the iPhone was running normally except Safari won't open now (it will open but the page won't work and the URL bar/ google search bar won't respond)
I tried to boot tethered, and it seemed to work and took me to my lock screen but quickly went back to the apple logo.iFunbox quits unexpectedly everytime I try to launch it so I can't remotely uninstall the tweak. Cyber duck can't establish a connection with my iPhone either.
What do I do?
