calendar sync

i Have a bb 9700 and have not been updated versions regularly and now have issues with calendar sync from desktop to device.
Do i need to update my versions or can I sync with google? But then I would need to create a gmail account?
What are my options?

Google Sync has been taken offline a long time ago. You need to setup a BIS account with your carrier which you probably already have.
