thanks for posting this, i am also planning on upgrading to 4.1.... well that is if i have to in order to play new super mario brothers wii. my biggest fear is that new super mario bros wii will ship with a 4.2 update that you need to install in order to play, and i dont want to loose homebrew. has anyone heard or has any inclination that NSMB Wii will ship with a 4.2 update?
because its better to be on 4.2 and have a way for anyone to update to the latest firmware
4.2 has an update for nearly every IOS in your system
the only reason i can think of that people would want to downgrade from 4.2 to 4.1 is because 4.2 breaks region free for cIOSCORP and modchip users.
going from 4.2 to 4.1 lets you have all the newest IOS's available while having the region free options from 4.1
