I bought the Nokia 710 with the $30 t-mobile plan with a soft 5gb cap data and 100 minutes. I am trying to find a way to setup VoIP through Skype, google voice or any other app or method possible to utilize data connection thus not using voice minutes. Anyone know a method where this would be possible. I have read android had a dialer app that could be set to Skype as default for calls. Haven't found an option yet to do this with windows phone.
