    Hi, I just asked my carrier (Optus) to unlock my iPhone 4S 16GB. Now I am wondering whether is it a permanent unlock? For example, I know I have to restore in iTunes so that the unlock takes effect on my iPhone. Right now, my iPhone is unlocked but what if later I move to another country, restore it with a newer iOS in iTunes. Will it still be unlocked or get locked again?

    When you plugin to itunes, you should get following message : your iphone is now unlocked

    Yes, once its carrier unlocked officially then its forever unlocked and will take any gsm sim no matter what firmware you restore or upgrade to.

    I forgot to ask, can I activate my iPhone with another sim card in case I have to restore it or do I need my current sim card forever?
