Wii Firmware 4.0 Guide.,
Submitted by softchip on Mon, 06/15/2009 - 19:23Wii Firmware 4.0 Guide., To answer most of your questions.
I had a 3.3J Wii, and updated to 4.0 today to be the guinea pig and see what changes happen if you update. So I'm posting my findings here.
If you update to 4.0:
1.You WILL NOT lose your current Homebrew Channel.
2.You WILL lose the ability to install the Homebrew Channel with any version of the Twilight Hack if you don't already have the homebrew channel installed.
