i have google voice. got in back when google first bought grand central
i picked a local area code number, and was all hyped about it ...
and it kinda died, it still worked but little or no support for it , only forums and groups
so i really didnt use it much
it had VVM but since i was on dumb phone, it was not fully usable, i had to get on pc to play my voice mail
as for now it seems to be much improved, though some feature still not active on dare. though the auto transcribe is pretty damn cool. someone leaves a voice mail and i have transcript sent via txt message, the @ 80% accuracy makes it very entertaining also.
in my tests i received the transcript with in a min of hanging up.
i'm getting an omnia this week , i'll let you know how it works
