Delete calendar event from iPhone I received an e-mail with an .ics attachment and I opened it on my iPhone. I opened the attachment and added it to my calendar. Now I want to delete the event. How do I do that?

More Details:
When I open most entries in the Calendar app, they have an "Edit" button in the upper-right, and then a "Delete Event" button on the Edit screen. But not this Calendar entry.

I'm guessing that I can sync to my Mac and delete it from there, but that's not a good option since


I'm at work
I don't use my Mac very often
Deleting an entry from the calendar shouldn't require a 5 minute process


Update: Not only am I unable to edit anything about the event, but I can't even change the Alert time. There must be some way to edit events received via .ics.
Was it added to a calendar? Or as a calendar?

Go into the Settings under Mail, Contacts, Calendars and see if it was added as a full calendar.
