downgrading firmware

a guy on macrumors.com said this: READ MAINLY LAST 3 PARAGRAPHS
(thats what im referring to) and is that true?
This will NOT work for "any iPhone/iPod touch." This needs to be
made clear for anybody who thinks this is a one-size-fits-all
solution for everybody.
Apple cryptographically "signs" firmware releases these days.
This happens during the restore process, and unless Apple signs
off on the restore, you'll get an error message. Even if you
could bypass the error message, without the signatures specific
to your device for that iOS version, your device would never
boot up.
Apple prevents downgrades by refusing to sign anything but the
latest version of software. This is where Saurik's SHSH
collector and TSS server come into play, for those that take
advantage of his services.
The reason it worked for YOU is because you have a
second-generation iPod touch and you were downgrading to
something less than 4.0. Apple didn't start using
device-specific (ECID-based) SHSHs until 3.x on iPhone 3GS and
iPod Touch 3rd-gen, and 4.x on all other devices that support
4.x (including iPhone 3G and iPod Touch 2nd-gen). So, unless you
are collecting your SHSHs for each Apple software release, if
you are on 4.2.1 on your iPod touch, you would be able to
downgrade to 2.1.1 like you did, but you would not be able to
downgrade to 4.1 or 4.0.
Also, you didn't technically need iREB for this. All you used
iREB for was to get the iPod into DFU mode. You can do that
yourself, manually, using the power and home
buttons...instructions for doing so are in abundance on-line.
If you have an iPhone 3GS, iPhone 4, iPod touch 3rd-gen, or iPod
touch 4th-gen, you can't downgrade to any release without the
corresponding SHSH for your device. Period.

He is right. You NEED the SHSH blobs to downgrade for any
devices after the upgraded bootrom (Includes iPod 2G and iPhone
3GS with updated bootrom).

Well, I have the MC Model and I can downgrade to 3.1.3 without
SHSH Blobs, I just need sn0wbreeze. But I rather stay with
Black0ut, in my opinion, iOS 3 is buggy and ugly xD
