Hi I have some questions concerning the htc hero. I have no cell coverage were I am at but I have wifi. The service provider that I am using is sprints network. How do I get all of my calls and texts through my wireless router (wifi) at home without cell service? (The roaming towers here have low if no cell strength at all.) I have wifi only enabled and cell network is turned off. There has got to be a way that I can do this. I kno sprint has a 3g adapter that interfaces with the router to the phone, but I dont want to go that way. An app on a wifi phone doing basically the same thing would be nice and less expensive (without any add Hardware.) Any help or ideas?
