So, I finally nailed a 3.1 to 3.0 3G downgrade using "on file" ECID SHSHs. Will have more complete instructions for doing it tomorrow.

He doesn't say that the baseband will be downgraded. Not sure about the unlock possibilities, but you may be able to JB.

The baseband won't be downgraded because, as everyone says, it is impossible to downgrade the baseband. This solution will just sign the 3.0.x firmware, allowing you to do a restore from iTunes, just like you can for the 3G.

Yep, there are goona be lots & lots of the "I couldn't wait and updated to 3.1" gang who are never gonna be happy.

Back to AT&T or paperweight mode

I think a lot of people would rather a 3.1 JB, but this is great for people that can't live without their JB stuff. Kudos to Saurik.

i upgraded to 3.1 foolishly by rushing in... lost tethering which i do use quite a bit and a few jailbreak tweaks. (blank dock, %age next to battery, file downloads of 10meg+ for podcasts/apps).

So i downgraded (iPhone 3g) back to 3.0.1. 3.1 doesnt add enough to warrant upgrading to for me personally... not really bothered about phishing/genius mixes.
