Author: Could not find (found in Galaxy Extreme beta 1.1)
Editing: vin_ishere (added few new icons, changed scripts, replaced existing icons with good quality icons, etc.)
Here is a new fully working menu for s5560. Don't know the original author for this s5230 menu which I have transformed so anyone giving his name is welcome.
PS: Create "Menuwallpapers" folder under "Res" folder and copy wallpapers of your choice into it and rename them as 1,2.... upto maximum possible of 6.
