Just saw this cool app in Cydia called BundleID’s. What it does is let’s you get the bundle id to help theme the app.

So if your wanting to theme the dtathemes app icon you would find the dtathemes app in the list of apps and click on it. It will then show the bundle Id and ask you to dismiss it. This is a must have for themers. We hope to see in the next update that it tells the main icons name as well.

The devs info is here if you would like to see other stuff he has made.
