A week ago I had updated my iPhone 4 from iOS 4.3.4 to 4.3.5. It updated the iPhone okay, but then when I tried to jailbreak it with redsn0w 0.9.8b7 (The one with native compatibility to jailbreak iOS 4.3.5). It started the jailbreak process and then when it went to 'Installing Bundles', the progress par went to 100% really fast, it isn't supposed to happen as it has to do many other things. But then it booted up and showed a white Cydia icon, and the online solutions asked to boot tethered again. I did and got a proper Cydia icon but it would just keep crashing. I tried re-jailbreaking but there seems to be nothing I can do to jailbreak. Is there anyway to downgrade my iPhone to 4.3.4/4.3.3/4.3.2 as I already have those firmwares. Thanks, hope someone can get back to me as soon as possible.
