Hi Everyone, I have had my 3GS for almost 3 years now. I upgraded to a 4S this afternoon and would like to sell my 3GS. My question revolves around it being locked or unlocked. I bought the phone from an Apple store, I never jailbroke it, never did anything but use it. My contract ended almost a year ago so I am no longer on a contract. Is my phone "unlocked" because I fulfilled my 2 year contract? I see a lot of ads stating that people are selling their iPhones unlocked and I don't know if I can say this in my ad or not. Sorry for the dumb question...I just don't get this whole locked vs unlocked vs jailbroken thing. Thanks.
