hey wanna ask.. viber for n8 is available or still unavailable?

hey all, I really need your guys help here.

I'm using Android and my gf is using N8. I wanna know is there any free voip software that can let us communicate? Just some short sms-es and a 5 minutes call to her would alr cost me RM10+ per day.. sms now we using whatsapp, just figuring out for voip.

I know Viber is coming to Symbian soon. But however it's still not available yet if I'm not mistaken. Talk box and tango are not supported by Symbian. Any other else? Skype?
