How do I sync 2 iPhone 4s with one calendar

You have have in account setup on both phones in which the "Calanders" toggle is turned on. Very simple.

If you use iCloud, then just make sure "Calanders" is on in the iCloud settings.

Can also do this with most other email accounts like Yahoo!

Here's how I would do it (though I'm guessing there are other ways):

1. Log in to iCloud.com
2. Go to the Calendar
3. Make sure the multiple iCloud calendars are shown on the left hand side
4. On that left hand side, click on "Edit"
5. Then click on the "+" box that appears to the left
6. Name the new calendar you're creating as desired (e.g. Shared)
7. Then click on "Done"
8. Then click on the "Share Calendar" button to the right of the calendar name
9. Then enter in the iCloud email address of the person you want to share the calendar with

That should do it. Again, there may be other ways but this is the approach I would take.

Note that you can also share custom Reminders lists.
