    Your thread shows as resolved?

    Anyway, I bet the iPhone was jailbroken and unlocked when you bought it. And now that you've updated it, it is locked again. Try putting in an AT&T sim card in the iPhone. If you call from it, the iPhone is locked to AT&T. If you're lucky, you can get AT&T to unlock it for you.
