I’m still alive
Hey gang…my apologies for being out of touch for so long. I was stuck in the Amazon rain forest for a month…had a run in with a buffalo.
As far as GV Mobile v1.2 from the App Store no longer working – I’ve addressed this many times it seems, yet I still get emails. Google emailed me many moons ago notifying me of upcoming changes to the account login for Google Voice. I was in the process of updating GV Mobile to account for Google’s changes when Apple turned their back on US, removing GV Mobile from the App Store, preventing me to publish a fix for the login issue everyone is experiencing now. There is good news! If you jailbreak your phone, I do have GV Mobile on Cydia that works. There is no other way for me to provide an update – sorry. I have re-submitted GV Mobile to the App Store, but seeing as its been over 2 months waiting for approval, I don’t see that going anywhere soon. Send Phil Schiller (schiller@apple.com) a nice email and he might get it approved.
As for the next version, I’m still working on it, but with the lack of revenue, I’m having a tough time finding time to work on it. As you all may know, this is my night time hobby, which comes 2nd to pleasing my wife. 
If you want to see movement on GV Mobile on the App Store, I urge you to email Phil @ Apple.
