    I am thinking of selling an iPhone 4 on eBay and was thinking of unlocking it. It is past the two year contract commitment so I should be able to get the unlock code from AT&T. The only thing is, I have no way totest that it is really unlocked because I will not have a different SIM card to test it. How can I be sure that when I sell it, it is actually unlocked?

    At the iPhone hacks section.
    Buy a Tmobile sim on ebay.
    Its only like $1.
    Or borrow someone's sim for a few minutes.

    I believe when you unlock it and its restored through iTunes, it will prompt you saying "congradulations, your iPhone is unlocked"
