VonageScott writes “Vonage just released a VoIP WiFi phone… you can use your Vonage VoIP account on any public WiFi access point (but not at places that charge, such as the airport, Starbucks, etc). I’d love to see this phone modded/hacked to be used with other providers (I use Voicepulse).” Link. If you use EVDO, you could at least make a mobile hotspot (see how to) but I’m not sure what settings you can change in the phone for providers (if any).
