I've finally got qgvdial working on Symbian to the point where it might actually be a candidate to send out on to Ovi.
I've tested qgvdial only on the Nokia C7, but from what I understand, that should mean that it works on all Symbian s^3 phones.
If you're the sort who likes to live on the bleeding edge, then head on over to the downloads list and look for the one that says "Symbian s^3. Testing only".
This sis file may not last out there for as long as you'd hope. I keep updating it as I add bug fixes. It comes and goes as I do this. It will break stuff.
You have been warned.
