I there! I found I way to downgrade from 4.3.5 to 4.3.3 through customed firmware via snowbreeze. Although I have a huge bug issue . Sometimes the screen goes off without being locked and if iPod is playing , sound stops . I have to press hone button to reopen it and play iPod again. Any ideas??? I would like also to make a clean restore to 4.3.3 without customed snowbreeze firmware and jailbreak it with the latest redsnow which I fully trust. On 4.3.2 had no problems at all.I have saved the shsh blobs through cydia and tiny umbrella but I think that iTunes can't restore to 4.3.3 without a snowbreezed firmware. Any help would be valueable!
