There is possibly a way to downgrade to 2.2 from 2.2.1 with the baseband downgraded too.
Go to this site to read about how to do it.

http://www.iphonehacks.com/2009/01/stepbys...irmware-22.html

Many of them got stuck on how to restore the phone in recovery mode. The video will demo &  explain how to do it. You have to follow the sequence in the video strictly.

Hope this help to get your phone working.

The other way is to get the Gervey SIM unlock card for firmware 2.2. It has been proven to work.

can downgrade to 2.2 from 2.2.1 but baseband still can't be downgraded....."bad news"........

"iPhone 3G users: The Dev team should soon release updated versions of their PwnageTool and QuickPwn tools to jailbreak your iPhone 3G running firmware 2.2.1 or or use this guide to first downgrade to firmware 2.2 and then jailbreak it. But since the latest firmware updates iPhone 3G's baseband to 02.30.03, you will not be able to unlock it even after downgrading to firmware 2.2. You will need to wait for some time for the Dev team can unlock baseband 02.30.03."

baseband is like one way street..... only can go up but cannot go down..... so TS can use d Grevey Sim Unlocker n wait for d yellowsnow to update...

Not true. Many of the guys have actually got the baseband downgraded to 2.28 from 2.3.03.
The site is:

This is what was quoted and there are also many post showing that some have successfully follow the step and downgrade to 2.2 incl downgrading the baseband.

------ post from the site ------------------
One of our readers, ezio-xb just commented on our step-by-step guide to downgrade from iPhone firmware 2.2 to 2.1 to tell us that he was able to successfully downgrade his iPhone 3G back to firmware 2.2 and jailbreak it. We have updated the guide to downgrade from iPhone firmware 2.2.1 to firmware 2.2
------------------------------------

Have not tried this myself but I am using the 2.2 SIM unlock card & it works.

i assume u don't read carefully on those article released by DEV TEAM...... please bear in mind once u upgrade d baseband to 02.30.03 there is no way to downgrade d baseband back to 02.28.00 (at d moment). d whole article is only talking about firmware downgrade n not baseband downgrade...
if u think so easy to downgrade d baseband then y should apple released d baseband upgrade? is it for fun? difinitely to kill yellowsnOw user....
..get your fact right before giving any comment..
by the way if u want to prove us wrong.....why not u upgrade your lock iphone to 2.2.1 using itune and later downgrade it to 2.2 n show us d baseband

cheers...
