Not able to add an appointment to the calendar on 4S
I have a new IPhone 4S, and it is not allowing me to add an appointment to the calendar (the + button is not showing). Other methods (ex. SIRI or pressing a date for a few seconds) does not work either. Any thoughts on how to fix this? This phone is not using ICloud since there is another iphone on the same account and we do not want appts mixed up.
iPhone 4, iOS 5
