just gave it a try on my Pixi Plus running WebOS 2.1 now that the ROW version is released. I expected the worst but it's running just fine just like the original device menu did but with a lot better look and functions of course. The only thing that doesn't work is Flashlight (it just says Error), because no one figured out how to use the Pixi's built in flash for 3rd party apps (so this is not your fault, garrett)
So far so good, thanks a lot to Garrett92C !!!
BTW: German translation for Roaming is completely false. In Germany we use the English word instead
