I just moved all my internal calendar items on my iPhone over to Google and setup a CalDav connection with Google so my iPhone calendar matches Google and I can update the calendar on either and then share it with people. It’s quite handy really.
Note: If you’re trying the following, it may be easier, after moving your data to google, to setup an exchange connection with Google. This will allow push email with Gmail on your iPhone, as well as contact syncing.
Steps:
1. Sync your phone (to copy any items over from your phone that may not be on the computer) and export your calendar with whatever program you’re using to manage calendars on your computer. For me, it’s Outlook 2003. I clicked file, import/export, and then selected export, clicked the csv option, and then chose to export only my calendar.
You may benefit from choosing a small range of dates to export reoccuring events for, since Google doesn’t support importing of these dates. You’ll have to delete any you import and recreate them in Google Calendar to have them repeat.
2. So you’ve got a nice CSV file saved somewhere now, right? Now go to Google Calendar and import them (under the drop down arrow on the left, click export calendar).
This is where you can stop following these steps and setup an exchange server if you’re wanting to go that route
3. Setup a new CalDav connection to your Google account by opening the settings app and navigating to mail, contacts, calendars > add account > other > CalDav. Enter your login information as demonstrated below.
4. Your phone should now be syncing with Google every 15 minutes by default, but you can always change this in your phone settings under mail, contacts, calendars.
Optional:
5. Delete events from your phone calendar to avoid confusion. You’re still going to have both your Google calendar and the internal phone calendar, even if it’s blank, showing up under your calendar app. This step isn’t important if you don’t mind the duplicate events. This is unrelated if you’ve synced using the Microsoft exchange method.
Setup a new blank calendar in outlook, and sync only that selected calendar to your phone (click your iPhone under devices > info tab > scroll down to calendars > “selected” radio button > *your blank calendar name*).
Alternatively, you could simply delete the events from your phone manually. This is likely a tedious process so I recommend the above method.
