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
