I just checked back in on a service that I used to use - MemoToo.com - you configure MemoToo to connect to one or more of your Google Calendars (or other various sources) and then you install a SyncML client on your phone (there are several available - I use Funambol). MemoToo acts as your integration point for connecting calendars/contacts/tasks/notes from a wide variety of sources. What sets it apart from other similar hosted services is that MemoToo offers incredibly wide support for import and export data formats, as well as several open and published synchronization protocols. They even publish their own API.
