    Is it possible to jailbreak an iPhone 3G if it's been upgraded to fw 3.0 and downgraded back to the 2.1 fw?

    Well, since you have to Jailbreak to downgrade... Yeah!

    There's nothing stopping you. Only slight problem is you'll have the 3.0 baseband.

    I downgraded from 3.0 to 2.2.1 and tried to jailbreak using Qwkpwn 2.2.5. After following the steps, it says the setup was successful but when my phone tries to restart it freezes at the apple logo. I waited for an hour and nothing. Does the updated base band have anything to do with it? I'm an At&t user so I don't use yellowsnow.
