Have you tried any of the home transparency cabs from that site. I have tried to make home tab transparencies but they don't work w/2012. I'm changing the same files that he's changing on that site. I think it has something to do with the fact that we're cooking in WVGA files as well as the VGA ones. My home trans. worked but distorted parts of the home screen. It looked sort of like it looks if you install a WVGA cab on a VGA device.
I did make a cab of my fav. glass clock for 2.5. I've not seen this particular glass clock yet for 2.5. The numbers need a tad more photoediting to get them exactly perfect, but the very minor issues don't bother me at all.
I just noticed some new messaging advancements as of this morning on the 2012 port XDA site too!
