This how-to isn’t in the usual remit of this blog, but it solves a problem I’ve had for a while – I can’t use the iPhone’s built-in calendar functionality with Google Calendar - so I thought I’d share.

The iPhone 3.0 software update supports [CalDAV](http://en.wikipedia.org/wiki/CalDAV), an open standard for sharing and updating calendar information. Luckily, so does Google Calendar.

It should really be easier than this; one of the important aspects of integration through open standards isn’t just its possibility, but also its accessibility. This feels more like a hack than real functionality – but at least it works.

1. On your iPhone, press *Settings*, and then *Mail, Contacts, Calendars*.
2. Press *Add Account…* and then *Other*.
3. Press *Add CalDAV account*.
4. Follow the instructions for [enabling Google Calendar in Apple’s iCal](http://www.google.com/support/calendar/bin/answer.py?hl=en&answer=99358#ical). Specifically, this means using your Google account details for the username and password, and setting the CalDAV server name to be *https://www.google.com/calendar/dav/YOUREMAIL@DOMAIN.COM/user*.
5. I found that the iPhone didn’t pick up the authentication first time round – you may need to go into *Advanced settings* and re-enter them. The *www* in the server name seems to be important.

You can also do it [using Google Calendar’s Exchange emulation](http://www.ianfernando.com/2008/sync-google-calendar-with-iphone-3g/), but that never worked for me. As with this, your mileage may vary.
