Awesome. Dont' know what it's doing in the back end but now I have achieved a personal holy grail that I've waited for an entire year. That's to sync iphone contacts and calendar with either the web (gmail/calendar) or a client (thunderbird/lightning) (and I've managed to do all of the above).

"Provider" was the conduit between google calendar and mozilla lightning.

Learn how to sync google calendar/contacts with iphone at http://www.google.com/mobile/apple/sync.html

and you're all set. All syncs in real time from any device, in any direction, bilateral supported.

Sick.
