Is there a custom 4.0 GM ipsw, or is it the beta ipsw that everyone is using for JB?

    for the 3gs?

    when i try to create a custom ipsw with the redsnow and the GM it says it is not recognizing the ipsw.

    any help would be great.

    Step by step would be even better

    You can jailbreak the 4.0 GM, but you need 4.0 beta 4 as well. Point redsn0w at the beta.

    Sorry, Ivan's instructions are for the 3G. For the 3GS, you need to use PwnageTool and a modifieded bundle file to make a custom 4.0 GM firmware. iHackintosh has a tutorial. It's not for beginners, use at your own risk.
