    I'm currently on a jailbroken 3.0.1 3GS.

    I know how to JB, preserving my baseband while doing so. I also know how to restore a device to stock firmware. But it's not clear to me what will happen to my baseband if I choose to restore my device.

    I'm planning to upgrade to 3.1.2 (jailbroken), retaining my old 3.0.1 baseband. After the upgrade, are there any options to restore to a stock firmware without affecting my baseband? Note that I do not have a 3.0/3.0.1 ECID SHSH on file with Cydia, so a downgrade to older stock firmware will not be possible.

    Any suggestions, or should I just resign myself to upgrading to the 3.1.2 FW's accompanying baseband?

    Nope, with a 3GS and no SHSH, it's 3.1 or 3.1.2, both have 5.11.xx baseband.

    Might as well upgrade the baseband... 5.11 is already unlocked...
