The Photosynth website is currently host to two quite different types of media: photosynths and panoramas. I see that you have created some of both on your account.
The Photosynth app for iOS unfortunately currently only opens panoramas.
If you want to view your synths on your iOS device, you will need to download the free iSynth viewer app. It is not officially supported by the Photosynth team and will not allow you to zoom into the full detail in each photo, but it was made by one of the college interns, Greg Pascale, during his summer at Live Labs before he graduated and joined the Photosynth team. Get the app here: http://bit.ly/isynth
If you want to create panoramas from Windows, you should use either:
1) the free panorama stitcher from Microsoft Research, Image Composite Editor (although everyone just calls it 'ICE'): http://bit.ly/msrice or, alternately,
2) you can use a plugin for Photoshop or Photoshop Elements: http://bit.ly/pstops
