I upgraded to the MobileMe BETA. Not sure if this is a "beta" problem or something that would have happened even I were not on the BETA when I went to delete subscribe calendars. I have been subscribed to calendars for some time. Then I went to delete some calendars I've subscribed to (my wife's). For some reason I am unable to delete the calendars I'm subscribed to. They do temporarily act as if they are deleted, but when I start up ical again, they reappear. It seems that it's not truly removing them from the CALDAV server (or wherever they may be saved on MobileMe). I've attempted to delete them, then delete Plist files, etc. etc. I have deleted all of my calendars and reset them up, hoping this would trigger something...no hope. Any ideas? Any way to access the server that seems to be bringing these back each time I restart? The only reason I think they are on a "server" is because I deleted all of my calendars and they did delete, then added my MobileMe account back into iCal and they reappeared again.
