    Can someone elaborate on this instruction. I would want my iPhone to be able to be unlocked when I decide to sell it.

    Remember: Greenpois0n recommends a clean restore before continuing. Do not update to iOS 4.1 or iOS 4.2.1 if you need the unlock. Ultrasn0w does not support that baseband yet. The only exception is the iPhone 4. You can update to iOS 4.2.1 without upgrading your baseband by using following this tutorial.

    There's no unlock available yet.
    We would all like to have it too but unless your i4 is on the 4.0.2 firmwares bb or below there's not much you can do but wait.

    Clean restore is always best no matter what.
