Waninkoko 4.1 Upgrader ( i would recommend...) With DownLink
Waninkoko 4.1 Upgrader I would personally recommend this if you play Wii Sports Resort because it stops the VC/WiiWare Game Glitch.
Waninkoko has released a 4.1 System Menu Updater, this updater is for those that wan't to keep trucha in earlier IOS versions, etc.
Quote:[ DESCRIPTION ]:
- This application allows you to update your console's firmware, installing *only* the
most important updates (System IOS, System Menu, new channels...).
Thanks to this you can keep some features like Trucha bug that affected first IOS
versions.
[ REQUISITES ]:
- 150-250 free blocks.
- Internet connection.
[ HOW TO USE ]:
- Run the application with any method to load homebrew and the update will be done
automatically.

Also i would just like to add, I upgraded from 4.0 from 3.2 Using waninkoko's 4.0 Upgrader and Everything still works. I can still install wads, change theme etr, I expect this will alow you to do the same. The only thing i would remember before upgrading is that some of the themes you have got may not work with 4.1 so WATCH OUT.
