I don't think you can remove the BB Dimension themes but you can remove the carrier theme. Search the forum for ' CrackMem ' and download the app. There's an option in the app to remove the carrier theme. That's the easiest way.

You can remove stock themes, search the forums for reed mclay's thread on memory optimization. Its a little tricky, but I was able to do it, and the free space is worth it.
