Firmware update 2.2surprised a few people who accidentally updated their iPhone. If that happened to you, you now have 2 choices: either stay and 2.2 and wait for the Dev Team to come up with ajailbreak method for 2.2, or you can attempt to downgrade from 2.2 to 2.1.
I personally don’t have this issue. I haven’t updated to 2.2 but I figured that some of you guys may have, so I started looking for a solution to post here. The problem is there doesn’t seem to be a solution that works for one main reason: 2.2 updates your baseband and once your baseband is updated, you can’t downgrade it to 2.1 (not as yet anyway).
From what I read, only 2-3 people were actually able to get their iPhone back to 2.1 without issues but it is very unclear what they did exactly… Now let’s have a look at these different methods that supposedly show you how to downgrade from iPhone firmware 2.2 to 2.1.
Note that I haven’t tried this and I do not approve it. If you choose to try any of these methods, understand that you’re doing it at your own risks. If I were you, I would just wait for a new jailbreak method by the Dev Team.
I found the first method onMegaLeecher.netand here is how it goes:

You can then follow these steps to downgrade from iPhone firmware 2.2 to firmware 2.1:
Again, I highly suggest that youread the commentsabout this method…
