Worked brilliantly -- I've now got my officially unlocked 3GS back to stock firmware and re-jailbroken.

Can now get your GPS back in order or update to iPad baseband just to downgrade to an unlockable baseband with GPS(05.13.04) if you didn't want to face losing GPS with the iPad baseband before.

Funny thing is.. they say you can use stock IPSW's from now on...Must be for those who don't want to unlock anymore, or people with carrier unlock from ATT, since you need to preserve your 05.13.04 baseband to unlock using Ultrasn0w, which would still require you to use a NO_BB custom IPSW for that.

You're right -- but if you've been stuck at 6.15 for your unlock, this will bring you down to an UltraSn0w-unlockable baseband. You'd then have to play the preserve-my-baseband game thereafter. Personally, I'm very glad to have the official AT&T unlock and not have to worry about that anymore!
