Thanks guys, i actually have a google voice account but what little i have used it has proven to be fairly unreliable (incoming calls not ringing through, being routed directly to voicemail etc. Same thing with outgoing calls taking multiple attempts to dial.) Also, im not entirely sure but using the google voice means i will essentially need to change my phone # to the google voice, correct? It won't spoof my t-mobile # for outgoing calls/txt messages? Is it possible to make and receive google voice calls only over wifi? On my Pre it's still all done over the cellular network by dialing into google voice and having it make the outbound call.
