this is a  quote from the the bigboss website

Yes, 3.0 GM is released to developers. This is the final 3.0 release. There is no jailbreak for it at this time. Do not yet upgrade. There are rumors of people using the 3.0 b5 jailbreak tools. This is a terrible idea. It will replace most your 3.0GM with B5 components. You will not have a real 3.0 final any longer, instead you will have a hybrid 3.0 and beta 5. It’s a terrible idea. Next week when beta 5 expires, your 3.0 jailbreak could expire as well and you would have to restore all over again.Yes, some people may claim that they did this and “it works fine”. But as I just stated, it is not a real 3.0 final any longer. Definitely not a good idea nor is this something you want. Just wait a few days and you should be ok

yep iPhone Dev team just updated there blog and theye say:

“With all of the great stuff lined up for us with the 3.0 OS that Apple described today, many 3G owners may find themselves with itchy update fingers. If you find yourself with access to the 3G IPSW for 3.0 via the iPhone Dev Center program, and you are using yellowsn0w, do not update or restore to that official IPSW. You will lose yellowsn0w and find yourself unable to revert the baseband to get it back.

And for those wondering, yes the 3.0 OS is jailbreakable on all devices. It’s just those using 3G yellowsn0w that have to show some restraint and wait for PwnageTool to create a custom IPSW that avoids the baseband update.”
