You can't use yellowsn0w now. You should've used PwnageTool to create a custom IPWS which wont upgrade the baseband. You'll just have to wait for the Dev Team to patch yellowsn0w for the new baseband. 
I think there might be a way, but would require you to take the baseband chip out, and use a hex editor on it...

Some phone shops will do this, unofficially of course.
