I have an issue that I can't seem to resolve... I called AppleCare, and they too were perplexed. Basically, at some point a subscribed calendar was added to my phone in the 'Other' calendar area.. It shows, "US Holidays" and below it, "Subscribed". I've tried everything I can think of to remove it; nothing helps. If I try to swipe the calendar, nothing happens. Clicking edit, then going to the next page where I can change the calendar color lets me change color but NOT change the name, and the delete button is missing. There is no Webdav (or anything similar) in mail, contacts, calendars in settings. I've removed all accounts and it persists. I've opened calendar on my mac; not there. I've opened calendar on the iCloud website; not there. It doesn't show on my iPad which has the same accounts/settings. Anyone have any other ideas?
