ok I have iPhone 4 4.3.4 by a mistake I've upgraded it and now I don't know what to do i don't know how to jailbreak it or just to downgrade it to 4.3.3. I need HELP !
Why do you want to downgrade to iOS 4.3.3? The iOS 4.3.4 is good since you don't jailbreak your phone. So there is actually no need to downgrade from iOS 4.3.4 to 4.3.3 if you were on stock iOS 4.3.3 before.
