you can always change ur sd card. just copy all the files over to the new one.Since there seems to be an update on the compatible versions (11.3), so I bother trying to update my current "new" 3ds XL that is on 11.3?
There reason I ask is I am still waiting on my n3ds in the mail along with my updates microSD (32gb).
Can I just update my 11.3 on the standard storage that comes with it and then add a larger storage in later, or do I need to be using the SD I plan on using during the CFW process?
