Hi Celeste,
MobiOne generates apps with zoom disabled. This is for several reasons:
1) more mobile web framewosk include MobiOne’s phoneui.js are very sensitive to layout and scale. Thus zooming the UI goofs it up in some cases. One area is clashes with iScroll (we use this component for smooth scrolling in Panel component).
2) The Test Center emulator does not support pinch-zoom scaling cleanly.
Can you share some details of what you wish to zoom in on, e.g., a picture, map, …? Perhaps we can find a workaround.
