Is it possible, that PhoneGap implements an option to prevent the
UIWebView from bouncing, when the user scrolls to the very top or
bottom of the app, like mentioned here:

Preventing touchemove via JS ist not an option, because it completely
disables scrolling of any content in the app.
The bouncing completely destroys the look and feel of an native app!
