    My dad just upgraded his iphone 3G to a 4, and I'm wondering if you still need to jailbreak it to use it with an AT&T SIM card, or is it already unlocked?

    If he bought his phone inside the United States, it is locked and can only be used with an AT&T SIM card unless you jailbreak. If he bought it outside the United States (eg France) the phone is factory unlocked and can be used with any SIM card.
