Google just announced a new service for pushing Gmail contacts and Google Calendar updates to mobile devices. And now for you who have an iPhone or a Windows Mobile, you can  synchronize Google Calendar events and Gmail events using Google Sync. Similar to the Blackberry application Google released last year, Google Sync integrates a user’s Google calendar data with the phone’s native calendar. It also works with Google Apps accounts, but administrator approval must first be granted.
Google Mobile Blog explains : “Once you set up Sync on your phone, it will automatically begin synchronizing your address book and calendar in the background, over-the-air, so you can attend to other tasks. Sync uses push technology so any changes or additions to your calendar or contacts are reflected on your device in minutes .”
As always Google is labelling this service a beta and lists limitations which should keep existing NuevaSync users clear for the meantime. Namely:
*Only five Google Calendars can be synchronised with Google compared to Nuevasync’s eight
*Modifying recurring events does not always work
*Deleting recurring events does not always work
*Calendar guest attendee information is also not reflected
*Contact information is limited to two home numbers, one home Fax, one mobile (a potential deal breaker for some), one pager, three work numbers and one work fax number. No work on addresses
