Most likely this was said and I missed it, but there is a new Wii Shop Channel update.

I have 4.3 and all the IOS stuff, so I'm just wondering if it's safe to update.

This was released on 7th/8th September, and there's a thread about it here: [forum.wiibrew.org]

It was stickied for a while, but it is not any longer as most people now know about it.
