Just double checked and it is my phone rom, the defx gb build that has the rotate problem. The V4 build ( running in slot 1 ) I am running now, everything rotates but the main screens.
Miui roms are pretty good looking but I just can't find the right one for me. I too was wondering why they're not shown more love here. I'm currently running 2.6.15 but might go back to 2.2.10 cause 2.6.15 lags a bit & no flash.
