Iphone reminder is different I have IOS 7, and I use the default reminders app.

One of my reminders is different than the others in a good way.  It shows a due date as well as an alert time; and the task includes the name of someone in my contacts and it offers to call them when I click the reminder.





For the life of me, I can't recreate this.  Anyone know how I did it?
When receiving a call you can either Decline it, Accept it, Respond with a text message instead of answering (by pressing the Message button) or Remind yourself to return the call (by pressing the Remind Me button).

When tapping the Remind Me button, two options are displayed: Remind me later or Remind me whenever I leave this place. 

The reminder you're referring to in your question, is one of the Remind me later kind.
