Delete (Group) Meeting From Calendar I received an ical invite through gmail, which my IPad3 added to the calendar.  But now I'm trying to delete the event, and there is no option to do so.  

I found a thread of discussion which says the event can't be deleted if other attendees are included in the ical info.  The only solution I've seen, also from the same thread of discussion, is to make edits on your PC and then use ITunes to synchronize the calendar.

I'm dealing with employer equipment, where installing ITunes is not an option.  In fact, attaching my IPad to the PC is also not an option.  I need to find a way to delete the meeting request from the calendar without using a PC as a life support system.

Actually my REAL problem is that the original meeting invite started at 9:30am.  Then the organizer changed the time to 9:00am.  But because the IPad can't seem to modify or delete a meeting (with other attendees) once it is created, the ical updates to my IPad are being ignored.

How do I fix this?

Now, pardon me, it is time for a rant.

This is such a ridiculous problem.  This is the year 2012, yes?  Apple is the cutting edge of tech, yes?  And neither I nor others can delete or modify a calendar event that has other attendees in it?!?!?!  My frustration is multiplied because, on an unrelated note, I'm also dealing with the common problem of apple equipment creating duplicates of music downloaded from ITunes.  The recommended solution for this latter problem, is ALSO to rely on a PC and ITunes for life-support.  Really?!
In Settings -> Accounts -> iCloud, you can turn Calendar on, and then off. It will ask if you would like to delete all synced events. I said "yes" and they disappeared from my calendar!  In other words all of the group events with no delete option were deleted. 

NOTE: this deleted all group events.
