How do I sync Gmail contacts with my iMac's address book and my iPhone?
When I had Snow Leopard I had the Google address book sync enabled and I somehow managed to put a 'sync' icon in the menu bar.

If I remember correctly I added it from the "old" iSync application (unsuccessfully trying to sync with a Samsung phone).

Now in Lion I still have it and it allows me to manually force the update of my Google address book, but I can't find how to obtain it as the iSync app seems to have disappeared.
