Looking at zarza's instructions, it looks like you need at least version 4.1.0.364:
"1. Download and install Telstra Australia's package 4.1.0.364
2. Download and install Cingular's package 4.1.0.401"
This would parallel my experience playing with my 8700. The Today themes would not work with apps package .284.
So you can try it with VZW's 4.1.0.268 but I am quite certain that the results will be as bizarre as what I experienced
here.
