Yes, sorry, I didn't notice that very small icon said Obitalk. Either way, we're talking about the same thing. I deleted it later after the first time I followed your instructions, and again when I repeated them earlier today.
One important point: my legacy google voice settings still show "google chat." About ten minutes ago after nothing else was working, I noticed there was a "delete" button by it, so I figured I'd try deleting it and deleting the google voice settings on the device config and re-setting up. Google chat re-appeared.
Any other ideas?
