Nintendo Letterbox/SwapNote got new Colours

I know Nintendo of Japan, Europe, and probably Australia have published a new DLC for Nintendo Letterbox (or SwapNote in America and Japan).
However, I'd like to know a confirmation from (Nintendo of) America(ns), just to know it's a worldwide release, or America should simply get it a bit later on.

For Japan, go to the eShop, and you'll be prompted to Update your Letterbox App.
For Europe and Australia, it's basically the same process, but if you like to do it via QR Code:


Me demonstrating the Update (and Ice Climbers, but just skip that one):

I updated it but I cannot change the ink colour .

Press Left or Right on the D-Pad to change colour.
Note: You can have only 1 colour per Note.

Ah! Ok.

My 3DS is from America, and it didn't work, so I'm guessing that it comes out later in America. Not that I really use Swapnote at the moment.

I still haven't sent a note because I don't have anything to say. :P

Is there an upgrade system where you get things for sending a certain amount of notes?

Yes, there is.
The more Notes you send (or just save and not send), the more you unlock.

It seems America also has the update now.

Got it! Thanks!
