Just a heads-up - there's a new 1.4.3A update for DSi, don't know what it does exactly, but it's there. The update stopped my 2i from working - that being said, it's a HW4444 that I've never been able to get running on 3DS, and I'm reading that the new 3DS update doesn't affect other peoples' 2i cards, so I dunno, someone else should try and post back.
