Launch iTunes. You should get a pop up message about 2.0.1 firmware being available. Click Cancel.

Put the iPhone into DFU mode by doing the following: with the iPhone on, press and hold the Home and Sleep/Wake buttons for
10 seconds.
The screen will appear black. Let go of the Sleep/Wake button. Continue holding the Home button until you see this pop up
message from iTunes.
You should be at this screen.
Press Option and click the Restore button. In the pop up window that opens, navigate to the custom
.ipsw file that was saved to your dekstop by PwnageTool at the end of Step 2.
You will see various status bars, while the restoring process continues.
When the restore process has completed, BootNeuter 2.0 will launch automatically. In my case, since I was
already unlocked, there was nothing for it to do but reboot the iPhone.
The iPhone will reboot at this point. iTunes should prompt you to set up the iPhone.
Then this screen will appear, confirming you are on 2.0.1 firmware.
Here's the first screen you'll see. There's the App Store, and Cydia. On the next screen is Installer 4 Beta.
You can check your firmware and baseband versions here.
When you launch Installer you'll be greeted with this message. If you install Community Sources, you'll see that
there are only two packages right now...
