iH8sn0w announced that he is close to finishing the programs through which iPod Touch 2G (MC model)/3G users will be able to update to jailbroken iOS 4.0. For now I don't know what these programs will consist of, I don't think it will be a new update for sn0wbreeze but only a modification of the programs used in tutorial jailbreak for iPhone 3GS with new bootrom.
The release of these new jailbreak solutions will take place this evening, so if you own such a terminal, carefully monitor iH8sn0w's Twitter account because when they are ready, he will make a new tutorial especially for iPod Touch users.
If I have 3.1.3 will it work, or do I have to have 3.1.2 or SHSH blobs just like the other one?
All 3.1.2.

For the release tomorrow night. Here are the requirements:
http://bit.ly/aoWLrH
iPod touch 2g MC = no shsh blobs required.
iPhone 3GS / iPod Touch 3 == requires 3.1.2 pre-installed or 3.1.2 shsh blobs.
3.1.3 SHSH blobs cannot be used because the exploit was closed.
I know, that means all 3.1.2.
if I now have a 2G MC OS4.0 iPod, will I be able to jailbreak it or do I have to downgrade it? if I have to bring it to 3.1.2 how do I do this?
Yes, http://www.zaone.ro/2010/02/05/tutorial-cum-sa-fa... the principle is the same for iPod Touch.
but if I don't know if I have a SHSH/ECID file saved in Cydia? what I do? do i still follow this one?
Yes, if you don't have it, you don't have it and you can't downgrade.
I had jailbreak done on 3.1.3 done with spirit and I didn't look to see if I have it and I don't even know how to save it. that is, if I can't bring it to 3.1.2, I have no way to jailbreak it to 4.0?
I managed to downgrade them to 3.1.2. if ih8Sn0w appears at night, can I jailbreak it to 4.0 tomorrow? thank you very much for the help.
Yes, but you have to wait for a tutorial to appear for this. I will make one tomorrow and you will find it on the front page.
