Thanks Steve. Yes, I did the two-step process, moving my landline # from Comcast to an old AT&T phone I had. I waited until that was active on AT&T and then ported that number a second time to GV and paid the $20. The number works and I have changed settings through Google as well.
I see it in that GV link you posted so I'll just go through the re-unlocking process with AT&T for that old iPhone.
thanks for the help,
