Hi all- Probably a silly question... I have iP4 4.2.1 with the oldest baseband 1.59... I am already jailbroken on it. I am trying to upgrade to 4.3.1 with Pwnage tool. Do I need to first update my iP4 to 4.3.1 (using tinyumbrella to preserve baseband) and then run Pwnage tool? OR I can use Pwnage tool directly on 4.2.1 jailbreak? (This sounds too good to be true) Can someone please confirm?
