I just bought a blue 3DS XL from the source. it had (c) Nintendo 2012 on the box, as I was instructed to get. however when I got it home, Firmware 6.2.0 was on the unit. The source (radioshack), let me return it with no questions asked. so thankful for that, it was the only one they had. so.... did i miss something? Could use a little help. thanks! The serial number was SW40******* this is the 2nd one that was 2012 and not on 4.5. And my local ebgames only had one unit it stock and it was on 5.X drove 2 hours to get to these places, will go again in a couple days with more information, but i thought i knew all i had to. thanks in advance.
