Ever since putting iOS 5.0 on my iPhone 4. The calendar doesn't sync with my mac's calendar. Ive tried turning the calendar off and on. And I've noticed. When the calendar is "OFF" not syncing with iCloud it gives me the options to add "Events" but when its turned on I have no options. Anyone experiencing this or is this a known bug? And now the mail from my .me account I did move it to iCloud is not sending mail it receives mail but does not send at all. Did apple release a buggy software?
