    Hi,
    I've got a jailbroken 3gs (old bootrom) which is currently running 4.0.1 and I'd like to move to 4.3.1 (jailbroken of course!) while maintaining my current unlockability (Modem firmware 05.13.04). I know that there's been a new jailbreak for 4.3.1 and before I go ahead and do it, I wanted to see if there's an optimal way for me to do it such that I don't accidently upgrade my baseband or something. I have tons of SHSH blobs saved via cydia if it matters. I once found a site the allowed you to plug in your information and it'd give you your upgrade path options, but I can no longer find the link.

    I'd appreciate any help or advice in getting my phone up to 4.3.1. Thanks!
    -Jon

    Use Sn0wbreeze or Pwnage tool to cook up a customs 4.3.1 firmware, the restore your phone with this customs firmware to preserve your baseband.
