I have been using sipdroid with gizmo 5 and GV on my Incredible for many months now.It has been working well until this morning.I now get a 500 server Internal error trying to connect.If I switch over to wifi sipdroid connects fine. it seems sometime last night verizon started filtering gizmo5. This really sucks,I haven't called cust service because I know that will lead nowhere. Anyone else wake up to voip not working via 3g?
