Hey Nik,
Here's an update on our API situation:
Yesterday, we pushed a change to bypass mobile redirection for all paths applicable to API authentication. I tested this change out w/ Happening and it looks good to me, but can you take a look as well? (Note that if it doesn't work at first, you *may* have to clear Mobile Safari's cache & cookies.)
FYI, while playing with the app yesterday, we found another bug in our API related to friends' events. But other functionality such as watch/attend and My Events look good from my end.
