If I unlock my iPhone, can I still use it with AT&T?

[SephirothXR]

I read this in a tutorial with PwnageTook for my iPhone 3GS's 4.3.3

Browse for iOS 4.3.3 firmware, click Open. Next, select ‘General’. If your iPhone is on an official carrier, untick ‘Activate the phone’. If you want to use your iPhone on an unofficial carrier, tick this box.

I'm leaving for Chile in two weeks and would like to be able to use my iPhone there. However, I still want to be able to use AT&T in general. If I unlock my iPhone, or "activate" it, can I still use AT&T and then switch to another carrier in Chile upon putting in a SIM card? I'm currently waiting to jailbreak depending on a response to this question so it'd be appreciated if anyone could tell me soon

Ask AT&T to unlock it for international travel. They are generally doing it for many customers.

unlocking is a using your iPhone on any network including the one it was locked to.

activation is required to get the iPhone up and running using an authorised carrier sim if its locked and any sim if it's factory unlocked.


now the issue at hand, best to get unlock from carrier I.e AT&T and the. you can use it abroad and in the US on any network of your choice including you know what
