    I have an iphone 4S sprint (CDMA). I successfuly used gevey ultra S (multi network) to unlock it and used in Tmobile (GSM). Now if I want to use different GSM phone carrier like AT&T or oversea GSM phone carrier , do I
    need to do something like reset, start from the beginning or just put the
    different SIM card (over gevey card) in.
    I have tried to put an AT&T SIM card in but the phone shows NO SERVICE.
    I don't know it is the AT&T SIM problem (because it is an SIM took from
    an AT&T iphone 4 which has been disconnect) or I have to do something.
    If anyone have use gevey sim please give me some advice.
    Thanks

    Have you tried the Applenberry website.
    They have support information on the website on how to use their sim interposers.

    Yes, but I don't know when I reset using the white reset SIM what carrier do
    I have to select ? Sprint US ( the original phone lock to ) or Tmobile US ( the one it use now )?
    I tried to contact Applenberry because the instructions in their website is not
    clear about the reset.
