    you will need to unlock to use another sim.

    if you bought the phone outright it may already be unlocked.

    if you got it on a plan/contract it is probably locked.

    if you need to unlock your phone, you first need to jailbreak it.

    hope that clears things up

    If as previously mentioned, your phone is not already unlocked, you have to jailbreak your phone in order to then unlock it.

    My experience has been with ATT and Telcel (Mexico). I have an ATT plan/phone and did the two step procedure (jailbreak/unlock) to use the iPhone w/Telcel chip while in Mexico. Works great as a phone, and no problems with wifi. That said, I'm unable to access the usual features associated with 3G with the Telcel chip.

    I enquired about purchasing a iPhone chip only from Telcel but they would not sell it without the accompanying phone and a 1 or 2 year plan (shades of ATT). Not that big of a deal, as there are plenty of wifi spots available if needed.
