How do I set a default calendar-app in Android (Jelly Bean)? I've installed PocketInformant and use it as my calendar app on my phone with Jelly Bean. However, when I get appointment/calendar event reminders, it's the stock calendar that notifies me. This is a bit annoying, since I sometimes wish to edit the appointment from within the reminder. Clicking edit brings up the stock calendar and not PocketInformant.

Is there a way to set PocketInformant as the default Calendar app? Or at least make it the default app for showing calendar reminders?
Yes!  you should be able to clear the stock app from being the default calendar app by following these steps:


Go to the phone settings
select apps
scroll to the right two screen, to the 'All' section
scroll down until you can find calendar, click on it
scroll down the page and click the 'Clear defaults' button


Next time anything wants to use the calendar, you will be able to select which program you wish to use.
