I'm currently running iOS 4.2.1 on my 3GS, New Bootrom, 6.15 BB. I want to upgrade to 4.3.2 using custom ipsw. Now to preserve my BB, do I need to pick an ipsw that says 6.15 BB, or the one that doesn't mention BB at all?

Reason: removed custom firmware links
You ipad baseband will remain no matter what version you restore. You can only restore to custom firmware and all custom firmware will not touch your baseband, so you are good to go with that.
Cydia paid apps for download is currently down. But if you just want to restore to cfw and unlock with Ultrasn0w, you can still do that.
