In 2.2.2 hidden menu is in system but hidden.
Here is a way to active hidden menu.
To activate you need to create a shortcut to this hidden menu. You can do this with most replacement launchers and apps like BetterCut.
Example using LauncherPro (others will use a similar method):
1.Long press on home screen
4.Scroll down to and expand com.lge.hiddenmenu
5.Select HiddenMenu (first entry)
6.Enter Shortcut name
7.Click on shortcut to launch
8.Hit 'Thanks' below
Enjoy the vast amount of options and tests in there, and be careful as some are destructive.
