I haven't done this but I just want to know if i want to get rid of it for whatever reason but don't want to keep the hack on can i get rid of it?Right now mine is at 4.0u and i havent seen any hacks out for that yet. :(
Yes you can get rid of any loader. You can also remove the cIOS that the loaders depend on. Use Any Title Deleter to erase the Loader Channel(s) if applicable, as well as deleting IOS202, IOS249 and IOS250. You may not have all those IOS files installed. It depends on what you did to your Wii.
