someone please answer this question
I got my 3GS replaced under warranty and they gave me a (obviously unJB'd) 3.1.3 with the older bootrom.
There is no way to bring this device to a jailbroken 4.0 install atm, correct?
Curious as to what the method would be for a 'virgin' 3.1.2 3GS. Never upgraded to 3.1.3 or jailbroken before. It is a first day unit, so it should have the old bootrom. Would I jailbrake first under 3.1.2 then upgrade? Is it possible to do both under PT 4.0? not sure of the steps I should take.

My 3Gs is at 3.1.3 with a custom ipsw from PwnageTool. Do I have to restore to 3.1.2 before using PwnageTool 4?
I am getting a 1600 error in Itunes when I try and restore with the custom IPSW that Pwnagetool 4.0 made.
Nope. I assumed you were at 4.0 unjailbroken. You can just do an option-restore in Recovery Mode.
Try it in Recovery Mode.

I am getting the same error. Pwnagetool 4.0 makes the custom IPSW no problem, but every time I try to restore in Itunes I get the 1600 error.
My bad, I was going into DFU mode and not RECOVERY mode so that's why I was getting the 1600 message.
Here's what to do:
Disconnect your device from the computer.
Hold down the HOME button and keep it on hold
Now connect the cable until you see the Itunes logo or Steve Jobs on there
Now let go of the HOME button and restore to custom IPSW

•If you have an out of the box iPhone 3G you should restore using a PwnageTool 4.0 ipsw using DFU mode.

iPhone 3G and 3GS baseband unlockers (those who rely on ultrasn0w to make phone calls) should always be very wary to update their firmware, however our Ultrasn0w application will unlock all recent (including the current) 3GS and 3G baseband firmware versions, once you are jailbroken using PwnageTool 4.0, install ultrasn0w from Cydia and you’ll be unlocked.
I have been reading so much today on this that I have a feeling I am confusing myself.
I have a 3GS 3.1.3 Jailbroken with Spirit baseband 5.12.01 with the old bootrom. I know I can not use pwnagetool 4.0 in my phones current state but if I downgrade to 3.1.2 and jailbreak with blackra1n I believe I should be able to, am I right?
Thanks in advance.
