[Plugin Calendar] Calendar to subscribe/add to iPhone?

I am the admin for a Boy Scout Troop web site (www.troop908hughesville.com)

We have a calendar that we use to show Troop activities — meetings, fund raisers, etc.

One of the parents asked me last night if there was a way to add the Troop calendar to her iPhone. I thought that was a great idea.

Looking at my phone’s settings, I can add a calendar either through a CalDAV account or a Subscribed Calendar.

Do you know of any calendar plugins that use either of these two options?

Thanks in advance for your help,

Joe
