and it may trash your phone, so use this at your own risk. Also,
once installed, it will dis-arrange your MENU settings or any
customized settings that you made and you need to re-arrange
it to use the subfolders. Sorry no add/remove included.

Description:
Arrange the clutter of your Menu with SubFolders, once
installed you'll have 9 Template Folders in the menu level
having 6 sub-menus each, more than enough for your fickle
needs. You then have the option of deleting, renaming, moving
or putting in apps from the Menu Options .
WARNING: Before installing subfolders, just copy
c:\system\data\applications.dat to e:\backup.
So you could revert back to your old MENU Settings by copying
back the backup applications.dat as if nothing has happened
(You should then Press Menu>Options>Exit)
If helpfull, repute me and tell me what you think and
