I do not recommend installing google voice. It caused my phone to "screen" all calls when you answer them. Phone would ring, answer it, get a voice saying "do you want to answer or do you want to go to voicemail? Press 1 to answer." BUT most of the time, when you press 1and it dropped the call entirely. If I wanted the call to go to voicemail, I never would have answered it to begin with. Had to have Sprint tech support force the app off of my phone and then it started acting very quirky. Phone wouldn't ring at all when calls came in. Just sent to voicemail. Had to do hard reset, seems fine now. A lot of drama just to use google voice. I say skip it and stick with the regular voicemail options until they work the bugs out.
