It seems like Windows folks have an easier time in the downgrade process. So will doing this from Fusion work?
Got a tip for us?

Will downgrading from 3.0 beta be easier if I use VMware Fusion?

Just do it the easy way. I haven't heard of the Fusion, so for all I know, it could be great, but this is what I know has worked:
Plug in iPhone, get it on iTunes
Shift + click restore, select the 2.2.1 firmware, restore to that. iTunes will give you this error message, but it did downgrade.
Then use QuickPwn, and go through those steps, without adding Cydia or Installer. It will be on 2.2.1 after this.
Plug back into iTunes, and select your backup.
Voila.

Just plug it into Pwnage tool and downgrade to a custom 2.2.1. Then click restore in iTunes and it will restore it to 2.2.1 from your last 2.2.1 backup.
You can use QuickPwn too and do the same process.
The reason I say use Pwnage tool is because I always got an error trying to downgrade with QuickPwn, but then again I have heard success stories too.
The reason I say restore again is because using Pwnage you will have a custom 2.2.1 firmware.
EDIT: And the key on a Mac is the alt/option key next to Command and Control
So there's no need for all of that iRestore / terminal stuff I've been seeing in some downgrade instructions?
No, just do this:
Step 1. Turn off your iPhone.
Step 2. Hold down the power and home button.
Step 3. When you see the Apple logo, release the power button but continue holding the home button down.
Step 4. Open iTunes and wait for it to tell you that its in restore mode.
Alternative Method:
Step 1. Connect iphone to USB then listen to the sound when it connect and disconnect.
Step 2. Hold the home and power buttons until hear the disconnect sound then release power button.
Step 3. Wait until you hear another sound then release home button.

You need to use a powered USB hub to fix DFU in 10.5.6
A Hub is just extra money. I have used this with no issues. But then again I guess one persons success can be another persons failure.
