    If your SIM slot is unlocked, yes. You will still only get 3G services however.

    If you have a Verizon iPhone 4s, it doesn't need to be unlocked.

    You can't use 4G in an iPhone, the current iPhones only support 3G.

    The iPhone 4S uses HSPA+ on AT&T, whereas the other iPhones don't. Therefore if you don't have a newer sim card on AT&T and haven't changed to a "4S" data plan then you won't get the HSPA+ (4gdata speeds).

    Iphone 4S= 14.4mb per second
    Iphone4= 7.2mb per second

    FYI HSPA+ is just a sudo 4G network.

    I know HSPA+ is not really 4g, but you still can't hit those speeds without an updated sim card. They shouldn't have called it 4g to begin with. It's 3G enhanced.
