    Hi everyone,

    I need to unlock my iPhone because I have some international travel to do and want to swap the sim out. I don't care about jail breaking, just unlocking. I would like to use on of the many tools available online (i don't mind paying) but have no idea which one to use. Any suggestions?

    Thank you,
    B

    Gevey SIM is your only bet unless you have baseband 01.59. Requires jailbreak.

    better way to ask is what firmware and baseband are you on.. settings/general/about

    I too was looking to unlock (to use on T-Mobile, though), I'm thinking about buying a phone off of Craigslist. It's an iPhone 4, and the guy says it has iOS 5.1 and baseband 04.12.01. Is there any way to unlock this, or is my time better spent elsewhere?

    Thanks in advance!

    damn

    i also have modem firmware 04.12.01 on an iPhone 4. so it sounds like I just need to trade in/up to an iPhone 4 or 4s factory unlocked.

    If I am not wrong, 04.10.01 is the last BB on the iPhone 4 that can be unlocked using the Gevey SIM. As already mentioned, with BB 04.12.01, you are SOL.

    does it have to be jailbroken in order to do so?

    i am trying to find an iphone 4 to buy, as it will be used in another country in asia.

    what is the only base band not able to be unlocked right now?

    You don't need to be jb to use a gevey.
    The highest bb on an i4 that can be unlocked is 04.10.01
    Anything higher than that you cannot.

    You must have a CMDA phone
    As far as I know, there is no sim interposer to unlock your phone

    Yes, you can never unlock a verizon iphone 4. Those are CDMA only iphones. They dont even have a sim slot so I dont know how you thought you could use it internationally to begin with.
    GSM or AT&T iphones on certain baseband versions can be unlocked, not any AT&T iphone 4.
    So do your research so you dont waste your money.

    The Sprint CDMA iphone 4 has no sim slot either.
    The Sprint iphone 4S does have a sim and if its unlocked officially by sprint for international use you can use the GSM side with any carriers sims outside the US.
    But you gotta make sure the original owner has requested an unlock for international use. Same goes for the verizon 4S iphones.
    If the network didnt unlock it for international use and the seller just lies to unload it when you go outside the US and stick an international sim it wont accept it.
    Your best bet would be to buy a factory unlocked iphone 4 or 4S.
    You want to risk getting a CDMA iphone for cheap most likelly you will get a blacklisted lost or stolen US CDMA iphone that will not work with any international sims.
    Up to you and the risk you want to take. Its your money.

    Actually 4.3.5 firmwares baseband or older.
    5.0 and 5.0.1 stock baseband is not unlockable.

    would be unlockable if they updated it to 5.0 or 5.0.1 and preserve the baseband? not if they did a straight update to 5.0 or 5.0.1?

    Yes, If they preserved the prior bb then it's ok.
    But find out for sure.
