I was previously using the skin posted in mp3car for my TyTN II and it was passable except MyMobiler always acts up after a few runs in CF.
I've since change my phone to Touch HD too. I'm also looking for plugin/skin for my it. I've found
WVGA HTC Touch HD Skin (Vertical AND Horizontal) but however, MyMobiler only works in landscape or portrait one at a time.
It'll be a waste if it G-Sensor cannot be put to good use anytime we want it. I've found
Pocket Controller-Pro does support landscape and portrait on the fly. The only thing is the lack of a good skin without the bezel but with buttons that does not take up too much of the screen so it can be finger and eyes friendly. And also some way to alway maximize the screen in both modes.
