    I know this is not an iPhone forum and I will post it over on iMore, but people here seem to know alot about iOS as well as Android and more people post here so I thought I would ask here.

    Verizon is SIM unlocking an iPhone 4S for me, so apparently the Verizon iPhone 4S has a GSM radio because it is not a 4G LTE device so there is no reason for it to have a SIM card on Verizon.

    My question is, if the iPhone 4S is SIM unlocked, does that mean that it can be used on ATT or TMobile? The reason I am asking is because on some verizon iPhone 4S listings I see that it is unlocked for international GSM carriers only, not ATT or TMobile. How can that be?

    Apparently there is a MCN/MCC restriction in the firmware that prevents using an ATT or T-Mobile SIM in an unlocked VZW iPhone 4S. You can however use a foreign SIM in it and when in the US it will roam on ATT.
