Trying to untether 4.2.1 on my iPhone 4 using redsn0w 0.9.7b6. I do a fresh restore of iOS 4.2.1, the first jailbreak works fine and allows me to boot tethered. Second JB starts and seems to work just fine, until it gets stuck at "Installing Bundles" and won't move past that. I've tried about 4 times now and I get the same result every time. I'm preparing now to downgrade to 4.1 again until a legit untethered jailbreak is released, but I was just wondering if anybody else had this problem and if they did, what you did to get around it. I've searched all over for an answer, I've seen other people stuck at the same point but never got an answer.
