Looking at zarza's instructions, it looks like you need at least version 188.8.131.524:
"1. Download and install Telstra Australia's package 184.108.40.2064
2. Download and install Cingular's package 220.127.116.111"
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 18.104.22.1688 but I am quite certain that the results will be as bizarre as what I experienced here
