Three questions...
1) How bored are you?
2) How friendly are you?
I can see portions of those last three digits. Meaning, I believe my FC looks like this...
2322-8288-612*
or
2322-8288-613*
Third question...Would you be willing to try and add all twenty possible FC combinations, see which ones it will really add, tell me when you have added them, and then go onto wi-fi?
