This is a discussion on Calendar problems with new IOS 5 update on Iphone within the iOS Forum forums, part of the iPhone Forum category; For those that don't have the + sign, have you upgraded to 5?...
I had the same problem and have tried what was suggsted but it hasn't worked for me. I think I had all the appts on a paper diary, time will tell, so I have reentered them but birthdays are all gone.
My entries have come back, I didn't even do anything. I noticed that some of my entries were entered twice I wondered what I had done to make that happen then it dawned on me. I don't know where they went but I'm glad they are back. Maybe they got lost in the cloud.
I am also experiencing the same problem. Updated my iPhone 3G from OS4 to OS5.01 Before I updated, I upgraded my iTunes. Now I can no longer add calendar entries. The + sign is missing. Very annoying as the calendar is something I really rely on. I ignored the best piece of advice a software developer can ever give you: "Don't upgrade your software until at least the .1 release." Anybody know of a solution? How about you folks at Apple Support hovering out there? Thanx in advance. Rick.
your calendars just got moved to a calendar that you are currently not viewing. Hit calenders in upper left corner and then Show all CAlendars on next screen and then done
