Cool, so simple - thanks! So it can be done with any file manager.
I've just successfully frozen the preinstalled "LGWorld.apk" by renaming it to "LGWorld.apk.bak". As soon as I had done this, a message popped up, saying "Deinstalled", and the icon disappeared from the app drawer, and also the update for "LG World" vanished from the Market app.
