Hmmm... I need help thinking through this... I originally had 3.0.1 FW that was JB by redsn0w. Unlocked Carrier baseband (04.something). Given the circumstance, I don't really need to unlock my iPhone, at least not until next year, so I decided to go ahead and BlackRa1n my iPhone. Everything was successful. Now.. I have 3.2.1 with Baseband 05.11.07. There is another carrier update that is asking me to update when I connect to iTunes but I haven't done so yet, I just keep cancelling. The question is the following. I plan to purchase an Macbook Pro next week. Although I don't need it, for completeness Pawnage of my iPhone, I would like to also unlock it. So.. Theoretically, considering I have an ECID file with Saurik. (At least that's what Cydia tells me when I launched the application on 3.0.1). Could I revert myself back to 3.0.1, revert baseband to 04.something and then use Pawnage to do everything over again but this time, keeping the ability to unlock?
