I don't understand; can you not just download the new 2.2.1 firmware (NOTE: download ONLY) and use PwnageTool to make a custom 2.2.1 that will preserve the baseband? Then use iTunes to update to the custom firmware?

EDIT: Nevermind. 2.2 is needed for the 2.28.00 baseband.

You'll have to find 2.2 online somewhere and use iTunes to restore to that. Once you're there, you can then use PwnageTool on the new 2.2.1 firmware.
