icons on my ipod touch doesn't change when applying a new theme!

[x00JuGGiE00x]

I realized that if you download an application from cydia or installous with a theme applied the icon changes. But with this, once applying a new theme from winterboard the icons don't change. It stays as the last theme's icons.
iBOB RS Theme:

Return of the CrazyBots Theme:

As you can see, the iBOB RS icons still remain. This happened because i downloaded it from installous/cydia when i had the theme applied.

Please help me!

First of all, piracy is not allowed here on MacRumors. Second, the icons aren't changing, because the developer of the theme hasn't made icons for them. In order for all your icons to change, the developer must make a new icon picture for each and every one of your icons. Its a long process, but looks really nice when its done.
