After quite a bit of head scratching, and googling I've managed to get my head around the orietation detection on the iPhone and the panoramas now display properly in both portrait and landscape mode. Also there are New Orion Expedition Cruise panoramas are online.
I've moved the site to the Red Square server so the site is now available at http://www.redsquare.com/360
note: You can view pages in a normal browser but the panoramas only work on iPhone.
Update: March 17th. I noticed some degradation of the cube faces when viewing over 3G so I've updated all of the cubes from .jpg to .png and it seems to have resolved the issue.
Update: Feb 16th: I’ve updated the iPhone 360º Panorama site with a new skin and I’ll be uploading new panos shortly.
