My sister has a old iPhone she wants to unlock and sell on ebay. After some googeling around, and looking through the forum, I'm at a loss. Anyone have any insight on how to do this? Thanks.

You need Spirit.

Open it, plug in your device, click jailbreak, and ta-da it's done

That will jailbreak you device. In order to unlock it, open the Cydia app on the phone and install ultrasn0w. Then the phone will be unlocked.
