I made a website around my virtualtour with rpano and used html to overlay the flash video ( I needed it for an aditional menu ).
Now for normal devices with any browser it works great but when I use my iPhone and iPad the overlay html is not displayed because I guess he use another library to render it well on i-Devices.
Here you can find my code : https://gist.github.com/2301394
So the problem is that I lose my #menu div on i-devices.
