Place your finger on the icon of the App. Hold it there. Wait for all icons to do the wavey thing.
Drag the desired App up to "Favorite" heading. Let go of it and it should be a favorite.

The trick though, is to drag it from the "All" tab, this will copy it into favorites, and also leave it in it's original category. Otherwise it does a move and not copy...
