Alright I've read enough things, seen enough videos, and had enough friends who have now convinced me drink the Koolaid and jailbreak my iPhone 3GS, but I am running 3.1b3 (yes I'm a legit $99 paid developer). Is there a way to jailbreak my phone currently? If not on 3.1 is there way to downgrade my firmware and baseband back to 3.0?
