If anybody could provide us with the 4.0 version theme of O2 that would be awesome. Not quite sure if in that version, you would be able to move around the application list.

Currently, I only have version 3.8.

There is not a 3.8 version of this theme - only 4.0. If applied to OS 3.8, it does not work correctly. If there has been any modifications, the latest could be found in OS 4.0.2.32. Look for my thread on the new way to install themes for instructions on how to install it on a 7100t (or 7100v, or 7100r, or 7100g) with the OS update.
