I'm trying to create a reminder calendar so I can add and delete reminders. It is actually working well on the devices I use (iPhone 5/4S/4) but on certain client devices which are still iPhones - I'm getting this error below about the account not supporting reminders.

Here is the workflow:

```
* Init the event store.
* Request permission (check its granted for Reminder types) (iOS6+) for lower we just init.
* Create a new calendar, local storage, type = Reminder
* Save calendar to get its Identifier.

```

Works most of the time, this appears on some devices - 

```
Error Domain=EKErrorDomain Code=24 “That account does not support reminders.” 

```

Permissions are granted and checked under Settings, Privacy, Reminders. I can't find anything in the docs about the conditions under which you'd get this error.

Thanks!
