I remember once I was using VNC on my iPhone, in order to remote manage it from my PC. I was using it to run a script on my PC where my mouse would send clicks on specific points in the screen, to keep-alive and send clicks on specific areas for game-botting reasons. When doing so I had the 3G connection off, so when VNC server on my iphone was ON, only the internal wifi network would be able to access the device, and not someone via the 3G IP.
