If you were to buy a gateway today before the 9.0-9.2 update hits, and your 3DS is 9.2, would that mean it's possible you won't be able to update the gateway to support the higher fw and would need someone with 4.5 to do it? Sorry if this has been discussed already
I think GW said that you don't need older firmware device to update your gateway card. You just update it from your computer.
