Sorry if this is an obvious question: So, I have an offer to buy an unlocked 3G from a dude in Italy while I am here. If I buy it, can I use it in the states? I am not in the states and don't know how the USA iPhones are, so would I be able to use mine with any carrier? Would it be as easy as, say..Verizon simply putting in a SIM card? I am only buying it because I travel a lot and would be able to use it in any country. Would Verizon even let me use it? Strange. Americans are always bragging about their "freedom", but I am laughing at how I can't even buy a pre-paid card to use my phone, like in, oh...90% of the rest of the world. Qatar, Vietnam, Cambodia, Thailand....you might call these 3rd world nations, yet I have the freedon to use a pre-paid phone card with my cell phone without getting stuck in a *****ty 2-year, expensive contract.
