Someone please answer, I got a used original 3DS for my friend, it came with a 2GB SD card, if I hack the 3DS with this card in the 3DS it came with can I later just move all the contents to another SD card? I told my friend if he wants to fit more stuff he will need a bigger card. But when you hack the 3DS is the stuff needed to hack it tied to the SD you used in any way? like once the 3DS is hacked can I just move everything from the 2GB SD card to the newer bigger capacity? or will I need to hack the 3DS again or something because i'd be using a different SD card?
Also, which is the easiest way to hack the 3DS currently?
As someone who upgraded his SD card today: Yes, you can hack it on one SD, and then later on just swap for a bigger one. Make sure you format it to FAT32, then just copy all the contents in the old SD and just paste them on the new one.
Regarding hacking, i think the general consensus is following the guide from 3ds.hacks.guide (sorry i cant post link)
