    Hello, I have not posted here in along time.

    Questions, I have Sprint Service, If I call them, and tell them I am leaving the country, and I want to use it out of country. Will they unlock my phone.
    I have the Iphone 4S
    If so then can I put any Att Sim card in my phone, will it work.
    I want to cancel my Sprint Service, and go back to Att, but I need to pay $320 to end my contract, and get the new Iphone 5.
    I think I can sell my 4S for $350 unlocked on CL.
    It will still cost me less, then paying 649 for the Iphone 5.
    Also I can get rid of sprints super slow data speeds im getting .6 to 1mbps on my 4S.
    I need faster.

    Thank you for your help.

    Ok, How does that post answer my question?
    Will they unlock my Iphone, and will it work on Att network or any GSM network?

    Thankl you,

    i believe sprint is a CDMA / EvDO carrier. so unlocking it will not work on ATT which is a GSM carrier.

    I believe your right, but I thought the 4S had both chips inside it, for GSM and CDMA, but I could be completely wrong.

    I have a Sprint iphone 4s. I had a gray market unlock done. It works great now. Upgraded IOS twice without a problem. Used it in the USA and overseas. The website that unlocked it no longer lists Sprint. ??? Maybe give them an email. The 4s CDMA does have a sim card slot. (World phone) The 4 CDMA does NOT.

    i did more research and raderson79 is correct. the sprint/versizon iphone 4s does support GSM. so, unlocking it will work with ATT.

    I spoke with Sprint, and they said plug your phone to I tunes and do a restore and it will be unlocked.
    I then asked them if I go to another country and pop a sim card in will it work they said yes.
    I called the t-mobile store here in cali, and asked them will it work and he was unsure, but they did say I could go in and try with a sim card they have instore.
    So It seams like it will work but im not sure.

    I think Sprint will only unlock it for non USA providers. That is why I used a gray market service.
