Hello I have trouble restoring my iphone back to iOS 4.3.3. Currently it is jailbroken with 4.3.3. Now I want to unjailbreak the phone back to its original 4.3.3. I go to iTunes and try to restore it back to 4.3.3, but I get an error device isn't eligible for build. I have tried unchecking TinyUmbrellas host files box, but the error still shows up. How can I remove the jailbreak from this phone while keeping it at 4.3.3?
