baseband upgrade for custom firmware 3.1.3 with bband 5.11?
is there anyway to stay at 3.1.3 but to manually flash the baseband to 5.12 since this iphone 3gs is giving me a headache trying to unlock with ultrasnow or blacksnow RC2
no shsh saved unfortunately and the guy used a custom firmware that put it at 3.1.3 but kept the baseband at 5.11
Yeah.. there are two ways:

This is for OS 3.1 but can be adapted for any 3.x version with the right decryption keys from Firmware - The iPhone Wiki
Big advantage of this approach, no need to reload the OS on the iPhone.
Disadvantage - more technical.
The other approach - needs to be tested - but i am 99% sure it will work.
Get PwnageTool 4.0.1 and Pwnagetool 3.1.5
First... open the 3.1.5 DMG and control-click on the Pwnagetool icon - select "show package contents" then navigate to Contents/Resources/FirmwareBundles/
find the iPhone2,1_3.1.3_7E18.bundle and copy it to your desktop.
Then open the 4.0.1 DMG and copy Pwnagetool from there to your /Applications folder. control-click on the pwnagetool in /Applications - select "show package contents" then navigate to Contents/Resources/FirmwareBundles/ then copy into this location the iPhone2,1_3.1.3_7E18.bundle you extracted earlier.
Run pwnagetool and go to expert/advanced mode. If you have a 3.1.3 IPSW on your mac, it will find it - otherwise you need to download that.
From this point on, you can follow any Pwnagetool guide you find - eg iClarified - iPhone - How to Jailbreak Your iPhone 3GS Using PwnageTool [Mac] but under "general" you will find an option to "enable baseband update" which you should tick on.
