iPhone Calendar Lost
I was messing with my calendar and deleted what I thought was my old partners calendar…when I did…I lost ALL of my calendar information. Is there any way to get it back?
iPhone XS
Depends. If you backed up the iPhone prior to messing with the calendars and you have not backed it up again since that time, you might be able to reset the iPhone and then reload the backup.
Unfortunately, that is a lot of work, and you will lose any other data that you might have added since the time of the backup.
