It’s “just” an iPod Touch vs. an iPhone - but yes, I’m now seeing that changes on the phone get sync’ed back up to the google account. It can take a few minutes though. And for some reason, at first none of the contacts (that I had entered online) showed up on the touch’s list. I could search for them, but they wouldn’t show up in the list.
Then I edited something - and all of a sudden they all showed up. but :).
What’ll be interesting is whether that works with stuff I enter when I’m not linked to a wi-fi: will it re-sync when I get connected again…
