Using the Original theme now. I like almost everything with it except a few small things.

I am not fond of the framed message bubbles at all. It makes the threads look cluttered. It would (in my opinion) look much better with a flat dark grey bubble (ala WP style).

Also not fond of the haptic feedback when swiping homescreens. For pressing app icons it's awesome. But it disturbes me to get feedback + sound everytime I swipe the screen.

Other than those two small things it's about as good as it gets!
