First, sorry about my english. I have tried to upload a panoramic photo to photosynth.net from my iPhone app, but when i'm trying to sing up, the app crashes. What can i do?
If you've signed in with a Live ID, then the crash you are encountering on upload is likely associated with that. We don't have a work around, but will have a new version out that fixes this bug in a few weeks.
