How to fix some mysterious problems.

Hello, I have an iPhone 3G[S] FW 4.0.1 BB 05.13.04, jailbroken and unlocked. Is there any way that I can keep that baseband (for unlocking) and upgrade to 4.2.1? Is there some software for this?

I've tried redsn0w 0.9.6rc8 but It only let me upgrade my baseband to iPad's 06.15.00, not letting me keep the one I have. If it's not possible to keep BB 05.13.04, would you recommend me to upgrade to FW 4.2.1 with BB 06.15.00 using redsn0w and gp?

Thanks, R.

You can if you use pwnage tool to make a custom firmware with the baseband you want. Then run greenpoison
