You'd have to update its bootstrap first, before being able to use it on your 3ds. Since it's on the latest 3ds firmware, you'd need another system (preferably a ds phat or lite, since those can't block flashcarts) to update. A dsi/3ds is fine, as long as your r4i gold can run on it (meaning, if the firmware is low enough for your flashcart to run, you can update using a dsi/3ds).
If your dealer is generous enough, they might flash it for you, prior to sending it to you (make sure you contact your dealer and ask them, though). Otherwise, you can download the updater on their official website and update manually.
