How do you delete a birthday from the birthday calendar on your iPhone?
Just another minor iPhone annoyance – but it seems unbelievable!
When I enter the contact information for my employees, I like to record their birthday. Birthdays have been a good excuse for all sorts of practical jokes around the Sage Internet office.
Recently, I noticed that birthdays of former employees still showed up so I decided to delete some of them. In most cases, I did not want to remove them as a contact – just keep them from showing up on my iPhone calendar.
Seems like this is not a simple task …it may not even be possible.
