iBlank will let create an unlimited amount of blank, transparent and completely invisible icons that can be used to create custom springboard layouts. The icons are created simply by pressing a button. Once they are created they can be positioned or removed like normal iPhone/iPod Touch icons. To use iBlank with iOS 4+ you will need to activate the WinterBoard theme called: No Icon Shadows – iBlank 4. This theme will remove the drop shadow that iOS 4+ adds to icons. Before installing, make sure that you have WinterBoard installed.
