My wife and I each have an EVO. I've set up both of ours to use google voice for making calls and sms. Periodically... maybe every couple days or so, google voice will just stop working. She can't dial out (just gets some generic 'fail' message) and she can't send text messages either ('send failed'). If she circumvents GV, then all is fine. The remedy? Reboot! WTF.. is this Windows or what?? Anyway, before I head over to the GV forum where I'm unlikely to get a response for some time, I'm curious if any other evo owners are experiencing the same. FYI - I don't seem to have the problem on my evo. Then again, I reboot fairly often because I'm often tinkering/experimenting on mine. For all I know, maybe I'd have the same problem otherwise.
