I had to make a map of what icons were on the homescreen (and in what order)...then bring up the whole menu (with the BB menu button) and then make a "conversion chart" to figure it out.
There seemed to be no rhyme or reason.
Once I had the map, I figured out how I wanted mine to look on the home screen, then used my conversion chart to put them in the seemingly-random order so I could get them to show up in the locations I wanted on the home screen.
The directions on how to do so, is in the same thread where you download the theme. Sorry I don't have a link or can't tell you more, but I read it when I was reading through the thread.
