    Unlocking 3GS on iOS 4 depends on your bootrom. If you have 359.3 bootrom, then you can jailbreak and unlock. If you have a 3GS with 359.3.2, then you have the new bootrom, and can't jailbreak, but can unlock. The caveat is that you need to JB before unlocking. So when the new JB tools for the 359.3.2 bootrom come out, then you can unlock it.

    If you want to downgrade, you must have saved SHSH files on Cydia's (or Saurik's) server. If not, then you can't downgrade. You'll have to continue waiting.
