Josef didn't fidget or scratch himself or fold his arms in the earlier version? I don't remember noticing that at all. Huh. 'Cause I think he's always done that in the desktop version.
Well, from what I can gather, the only way to revert to an earlier version of an app is if you have that version somewhere on your computer, i.e., either you had downloaded the earlier version of the app at some point from the iTunes Store to your iTunes library, or you'd synced your iPad to your computer's iTunes library prior to updating the app.
So the first question I would ask is if you happen to have the app in your iTunes library?
