    I heard that many people who used an unlocked Sprint 4s phone (via GPP, Sim-7 Gevery, etc...) lost their ability to use GSM SIM cards after upgrade to iOS 7. Apparently the betas worked but the GM did not.

    Anyone knows if any of those cards work? Again, Sprint iPhone 4s, so the pool of cards available is limited

    I heard the same.
    Its well known that once you update the firmware those gevey sim adapters don't work any more and you lose the unlock.
    You have to stay where you are or wait to see if they have an updated gevey you can buy for the new ios.
