If your phone has already been updated to 4.0 stock firmware there is not yet any tool that can jailbreak your phone. If you have your ECID SHSH on file for version 3.1.2 or earlier you can downgrade, jailbreak with redsn0w, then upgrade with a custom firmware created with PwnageTool. If not, you are stuck unjailbroken (and locked) for now.

Without the SHSH backed up you're not able to downgrade, and will have to wait for a jailbreak to be released.

If you don't have your SHSH on file, then you cannot downgrade. Apple will only allow you to install iOS 4.0 on your phone, and the only way to bypass that is to use saved SHSH.
