Hi,
If I get them to look ok in
iphone 3g will be tiny in iphone 4 & ipad.
then there might be something wrong in your case... (maybe a missing meta viewport setting in the html file?)
the krpano screen coordinate system is the same for iPhone3 and iPhone4!
that means the xml positions and sizes will be the same!
but creating device specfic layouts is also possible of course,
there are several ways to filter the device and when using dynamic code to place elements the stagewidth and stageheight variables can be used to get informations about the screen size,
best regards,
Klaus
