Using iFunbox, scroll up to user applications, find the app, right-click and select app inspection. Copy the app id (com.whatever.whatever).

In the Bundles folder, create a new folder, name it with the app id, then paste the icon into that folder.

The folder and the icon name are case sensitive.
Thanks again. Big help

For me, I can seem to change the icon if there already is a bundle installed on the theme, otherwise even if I add a bundled named correctly, it doesnt work
