ThemeIconMaker will not be upgraded for iOS 7 as iOS now applies the icon mask to all icons (including system apps) and because iOS now does what this app was originally doing, it is no longer needed on this version.
Compatible with iOS 4, 5 and 6
Did you ever had a theme that was missing icons? If yes, ThemeIconMaker is for you! It can add 99% of your Cydia apps in your theme with a click of a button! To use this app, simply tap the "TIM" icon, select your theme then click "Add all icons"!.
Note : this does not work will all themes, the theme should be able to automaticaly modify App Store apps, so I can get the mask and shadow for the icons.
When you want to uninstall a theme, you need to restore its icons first or it will still appear in WinterBoard
