While in the calendar agenda view, when I click on a date and press the BB button, I don't see a "Delete Prior" entry. Am I missing something? Did I imagine this? I could have sworn that I've seen this before but can't find it any more. Is this something that a theme could affect? I'm running the Blackberry Pro V2 Red theme.
I do not have a "Delete Prior" option in agenda view, either. I think maybe you imagined it... ha ha ha! I never looked for it before, so I'm just assuming it isn't an option in the calendar, since we both don't have it.
I could have sworn that this is how I deleted my facebook calendar entries before. I'm even finding some threads on google saying there is such a thing. Not sure that the threads are Storm-specific, though.
You must go to a date in the future in Agenda view. A future date beyond any date that you have calendar entries, i.e. 2011. Once at a future date, hit Menu and will see the Delete Prior option
