3GS downgrading 3.1 to 3.0 -- anyone tried this?

[GlassBullet]

I stumbled across this article online about how to downgrade a 3GS from 3.1 back to 3.0:
http://www.blogsdna.com/3911/how-to-downgrade-iphone-3gs-31-to-30-os.htm

Has anyone ever heard of this before or tried it themselves? If so, does it work? And do you know if it works with iTunes 9, or do you need 8.2?

It specifies 8.2 so I would guess it needs 8.2

Just be aware (with regards to unlock) Quote from webpage follows...

Please Note: With this Guide you can only downgrade your firmware but not baseband. Even after downgrading iPhone 3G3.1 to 3.0 your baseband will be still 05.08.01.

As of now, your unlock chances do not look good, but who knows ??

Yeah I saw that, but thanks for pointing it out none the less. I'm on AT$T so that's not an issue

Edited: sorry, I did not see that you were using a 3GS. You cannot downgrade a 3GS' firmware anymore.

It won't work. You can't downgrade on 3GS yet... that guide was posted back in July and Apple stopped signing older firmwares only 2 days ago.

Ohh I didn't notice the date before. Thanks

I downgraded from 3.1 Beta 3 to 3.0.1 at one point.

I know that doesn't help but I just felt like typing.

Betas were downgradeable, final is not.

True. 3GS is NOT downgrade-able at this time.
