Rated 5 out of 5 stars

Couple of people asked, so here is how i currently sync the iPhone with Thunderbird:

On google i use both calendar and contacts and sync both Thunderbird and the iPhone to it.

To sync google with the native iPhone contacts and calendar application i use nuevasync.com. There are other services out there but this is a no nonsense solution. It is free, it is flawless, and straightforward to install.

To sync google with Thunderbird i use add-ons: Zindus for the contacts, and "Provider for Google Calendar" for the Lightning calendar add-on.

Now i can change anything in any of these three places (google, Thunderbird, iPhone) and it propagates anywhere within a few minutes. Love it.

If i could convince myself to use IMAP then email would also be sync-ed all around, but IMAP tends to be slow, so i have resisted so far.

Needless to say, all of this is on Linux, but i suspect it would work on any OS, even windows.

This review is for a previous version of the add-on (0.8.4).
