an Asian Country? my dad lives in USA. i haven't asked him anything bout an iphone yet. i was just wondering if, he buys it from an apple store. and then sends it here (at Bangladesh) will i be able to use it? i heard that Americans need to get some contract or whatever. what if he buys it unlocked, i.e without any contract? will i be able to use it fully functional on any network provider here in this country?
