I have the newest iPad (with retinal display) and also the iPhone 5. I want to add my work calendar so that it shows up on both my ipad and iphone. However I don't see the "add calendar" button on my ipad or my iphone! I've been able to add my work calendar to my macbook ical, but i really can't figure out how to add another calendar in my ipad and iphone. I know I can synch with my macbook, but this is troublesome for me so I would rather just add my work calendar to my ipad and iphone. Does anyone know how to do this?? Please help.
