I just found out I need wifi: I'm in Decrypt9, can I just restart the 3DS to make sure it's on and have it connect to wifi? Also is this on by default: Can I back out and check it? It was brand new, just booted to test it when I bought it. Finally, to make the back up, do I need a 2nd SD card if I have 4GB MicroSD card? Thanks for any help you can give, I just don't want to brick this 3DS.
