My fiance Tina is a mental therapist and she regularly has appointments with clients. She usually uses her old Samsung phone as a calendar but needless to say it is not very practical. I recently “forced” her to get an iPod Touch and one of my sales argument was that she could use it as a calendar and that she would be able to sync it with Google calendar over the air. Note that these were just arguments I pulled out of my butt so she agrees to get an iTouch (yes, the iTouch is more for me than for her)…
We finally bought a 32GB iPod Touch and I started looking into ways to sync an iPhone calendar with Google calendar. I found many options but all involved some third party apps and that’s clearly not what I was looking for. I was very surprised that Apple hadn’t included this feature in the iPhone/iPod Touch until I actually found an article on JAIB saying that the new OS 3.0 supports CalDAV with SSL so your are technically able to sync Google calendar with your iPhone or iPod Touch, as long as you have internet access.
Here is how to set up your iPhone or iPod Touch to sync calendars with Google over the air:
1. On your iPhone, go to Settings > Mail, Contacts, Calendars > Add Account > Other > Add CalDAV Account
2. For the CalDAV settings, enter the following information. Note that your username should be the email address you use to access your Google calendar as well as the password.
3. Then tap “Next” and it should verify your information.
4. If you can’t get your account verified, tap “Advanced settings” and make sure that “Use SSL” is On, that the port is 443, and that your Account URL includes the sign “@” in your email address.
Now every time you add an event to your iPhone calendar, it will also show up on your Google calendar, and vice versa. You obviously need to have internet access from your or iPhone for the data to sync. Note that the sync is not immediate. It sometimes takes a few seconds but besides this, it works very well.
