I know this question has been asked but I thought my circumstances may differ a bit so figured I'd venture a guess.. Installed the HBC after updating to 3.4, went successful. Figured out it really wasn't what I was looking for, started realizing it probably was best not to potentially brick my daughter's xmas presents lol... I've purchased the Internet channel, but aside from some high scores, if formatting cleaned everything out, I wouldn't have any objections paying another $5 (to repurchase the internet channel) for my haste in figuring if I really wanted to do this... My primary concern is to make sure that in the future, should Nintendo decide to brick HBC users for some reason, that I can avoid it. It sounds like formatting will do the trick, but are there any semi-official (or REALLY smart) answers to this question that I can rely on? Googled and found yahoo answers, a thread or two on this forum, but nothing seemingly conclusive. Just wanna admit I wasn't prepared to jump into the scene yet, tuck tail, and wait a few weeks to see how often I even use the new console TIA for any help... I had heard going online may affect logs or such that Nintendo could find should I send it in for a warranty issue and as I use the Internet channel for youtube and a couple sites, I figured I'd check to see if that specifically changes the answer?
