I may have found a bug. I cleaned up the qgvdial directory and installed the latest build. It took a couple of mins to load up all my contacts and inbox (some of the text messages were missing, but that's a different issue).

When I switched to the 'dial' tab, on the top dial back selection bar (Google Talk vs. Mobile vs. etc.) it read "This phone ()" and didn't display my phone number. So, I tapped it and selected "This phone ()" again with the hopes it would recognize my number automatically but the app doesn't work now. It shows blank screens on all tabs (Dialpad, Contacts, SMS, settings)!
