I bought an acekard 2i a few weeks ago for my new DSi but as it turns out, my DSi was updated to 1.4u and I didn't know you needed at least 1.3 firmware or a dsl to update the card so I can use it. I'm going to order another one with a a pre-updated memory card. The problem is that I'm not too sure which site I should choose. I found one at 0shippingzone.com, shoptemp.com and leetmod.com. At 0shippingzone I can get it pretty cheap, and with pre-updated memory, compared to the other two. I just want to make sure with you guys that it's legit and I'm getting a working, real card. Also, is 4 GB enough? That's the highest they offer a 0shippingzone. Thanks.
