I don't sync my iPhone calendar with Outlook nor with any other program. I had a few dates and important reminders stored in it like giving me alerts 30 minutes and 1 hour before I have to leave my house for work. Recently, I couldn't open my iPhone calendar app. Whenever I try to open it, I either get a black screen, or a blank screen (calendar screen without the calendar/ just the background). However, the alerts do still show up.
Help!!
