Thanks for clearing that up. Can it show contact's name though? Because after I send a message using "SMS through GV" to one of my contact, the chat thread shows up with the contact's number, not the contact's name. Is it bug 8508?
And what do the "Ignore Dnd" and "Forward" in advanced settings do? The screen name is the callback number, so I guess "Forward" does not do that, it must have some other function.
