Hacking DsTWO DSi/3DS Compatibility

[Arsic]

So if I buy one of these and it says it's compatible with DSi, would it also work on a 3DS with some firmware updates? They should be the same, right?

With a firmware update, yes it will. All DSTWOs can be updated.

I received this earlier and yeah it works. Wasn't sure, so thanks for the reassurance.
