There is no need to manually export all of your iPhone calendar items to import them into Gmail. You can configure your iPhone to export all calendar items, and then import them into your Google calendar using Google Sync or CardDAV. If you use Google Apps for Business, you can use the Google Sync app to sync your calendar between your iPhone and Gmail account. Google Sync, however, is not available for non-business users. Personal users can configure CardDAV on the iPhone to sync calendars between the device and Google accounts.
