Have both 4.1.2 and 4.1.3.
Used 4.1.2 to build custom 4.1 IPSW, preserving current baseband. Put iPhone 3GS into DFU mode, then Option-clicked 'Restore'. Navigated to custom IPSW, selected it, then got the message: 'This will erase and restore your iPhone and verify the result with Apple.'
Is that what I should expect? None of the YouTube vids I've watched have mentioned this step...
Also, with Pwnage 4.1.3, I tried to build a custom 4.1.2 IPSW using the downloaded iPhone2,1_4.2.1_8C148a_Restore.ipsw, but when I choose this, Pwnage gives me the message 'Wrong Firmware Bundle Selected'. AFAICT, that's the right one for my 3GS... any ideas?
