Actually, no, going through settings menus to lock or unlock iPhone rotation does not accomplish what I'm talking about.
Again, no disrespect intended, please do not imply any, however...
I can't think of another app on the iPhone (where multiple orientations are supported) that requires you to go through menus to load the best skin for that orientation. If I turn the phone, the screen reformats automatically.
I do realize the issues involved, I.e. people would have to develop multiple graphics to support this (although let's be honest, this wouldn't have to be mandatory, it can be set up as a "use the skin if present, otherwise squash/stretch the current one").
So yes, it would mean more work.. But it's work nearly all iPhone app developers go through to remove the kludge were presented it's here...
Instead of simply rotating the phone and letting the app choose the best layout, we:
1) rotate phone to different orientation
2) tap screen,
3) tap main menu button,
4) swipe to get to next menu,
5) tap settings,
6) scroll to dashboards,
7) tap current dash name,

select new skin,
9) tap settings,
10) tap menu,
11) Swipe left,
12) Tap dashboards.
That is a crazy amount of steps, and very in-iPhone-ish IMO.
