So you mean pinch-zoom in the Browser/WebView. Check git, looks like it uses the same ScaleGestureDetector and auto-enables it if the device supports multi-touch (search for "void updateMultiTouchSupport"). I haven't played w/the WebView that much so not sure if just setting the useBuiltInZoomControls=false disables all zoom functionality or just the onscreen zoom buttons (again assuming the device supports multi-touch at all and useBuiltInZoomControls sets the flag accordingly). I seriously doubt they would have removed this in 2.2, if anything I would guess they just allow you set your own ScaleGestureDetector (since it's now public) and make the setNewZoomScale() method public.
