Schturman i just went through the files in Vesuri's package i was wrong initially...Since I'm using F2thak's themes i didn't apply Vesuri's package...

His package is simply an addition to the existing blanco folder instead of being a new theme altogether...

What his package does is add the following folders to blanco theme:
- calc
- clock
- libdialerui0
- liblockui
- music-suite

This way the phone uses the above .css files for blanco theme instead of using them from base folder instead...

also, he adds a new schema (meegotouchtheme-landscape.schemas) in /usr/share/gconf/schemas that allow you to set apps you don't want to allow to be displayed in landscape. By default he blocks touch screen lock and call UI from rotating...

So for your tweaks, there will be no difference on any device using his landscape packages...

Sorry for the wrong information previously...I too should read more before typing ...
