The Devices settings work perfect but remember you need the latest beta version.
You can set different settings for almost everything. For example I use 3 different autorotate settings as the speed is very different on iPads, Android and desktops.
Here is one I just changed the initial FOV on. Just opposite views and FOV on Flash and HTML5.

The code is simple.
<view devices="flash" hlookat="80" vlookat="-5" fovtype="MFOV" fov="50" maxpixelzoom="1.6" fovmin="60" fovmax="120" />
<view devices="html5" hlookat="-120" vlookat="0" fovtype="MFOV" fov="100" maxpixelzoom="1.6" fovmin="60" fovmax="120" />
You can even check this in Safari by using the Developer menu and User Agent option.
