I am using:
bootstrap-responsive.css from 2.2.0
The top fixed navbar is pushed out and becomes unfixed once I touch a text input that brings up the iPad's keypad. I have tested this on an Sumsung Galaxy and an iPad, but it only happens on the iPad.
I get the same issue on the Bootstrap site as well: http://twitter.github.com/bootstrap/base-css.html#forms

There isn't much we can do about this right now honestly—this is a problem on iOS's side, not ours. We could write JS to trick the browser into thinking it's moving to recalc the position, but that's not worth it. For now, we have to punt on this.
