I don't want to argue the on-line support w/ the people that want it, but if you want on-line you really need to go legit. I'm not being preachy and telling you to buy your games because of morality, I own a Gateway. I'd just like to point out the ban hammers that have happened on other systems that were hacked. Nintendo may be behind the times when it comes to security when compared to the rest of the industry, but they will get this shit figured out eventually and the strength of security on the 3DS has shown a massive improvement and shows that they are really stepping up their game. I suspect shortly after you get your on-line support you will be asking for a way to get your 4.X 3DS un-banned.
And consider that you will likely be banned from all on-line services: eShop, Spot Pass, MiiVerse, etc. On-line would rock, but I have a strong feeling that ultimately it would end in tears for us Gateway users.
