I have a Question about the Wii Friend code that you can find on your Wii address book.

Before I downgraded my Wii (3.4U to 3.2u), I was messing around with my Wii and checking out the system when I went into the Wii message board and I saw my Wii Friend addy and then after I downgraded I went back to my address book and it changed numbers.

Is this normal and will it cause any problems for me If I wanted to add some of my friends?.

Thanks to anyone who can help me and I am sorry if I posted this in the wrong place.
