So I decided to be a retard and jailbreak my iOS 5-running iPhone 4. It has springboard issues, and it kept resprining every few seconds, until it shut off. I knew it was a tethered jailbreak, so obviously I'd have to run Redsn0w again. I happened to get an error though. It got stuck on "Waiting for Reboot". Now when I try to downgrade, or restore, it just doesn't let me. My device build isn't eligible for the update. I'm making an appointment for the Apple store. Until then, any advice?
