    It does not work. 4s has a sim card but cannot be used on T mobile. Yes 4s is a world phone with cdma/gsm capabilities.
    It may work internationally when sprint unlocks the phone but will not work domestically. It is all about sprint.
    They sent me a code which is useless, sent be confirmation that the phone is unlocked which means nothing. After 2 years with sprint bad service I will give away the phone and buy a new one from T Mobile. After talking with sprint 12 times, trying 4 T mobile stores. Save youself the frustration.

    The correct frequencies probably are in there but besides the actual SIM lock there might be another software block on them. It may be possible to jailbreak the phone and then lift it. Most likely the information is available out there on the internet.

    The Sprint iPhone 4S cannot be used on other US carriers. ( unless you use a hardware hack; a Gpp sim, I do t recommend it).

    Good luck.

    If you ever get the urge again to give away, please keep me in mind. Current customer & that would make a great learning tool.
