The js file in the link above I believe is corrupt. It did not work for me but the concept above did the trick. Thanks.
Get the latest tourweaver 6.5.x.
Publish any tour in HTML5.
Look in the published folder with windows explorer.
Replace the tw-min.js file in your current tours with the new one.
Note: Your iPhone will cache the old js file for a day or more. To test out try it in another website folder. Or google up ways to delete cache in safari for iPhone. Changing any part of the url path will force the browser to not use cache.
Good thing they seperated there core app from the dynamic content. You don't have to rebuild each tour.
