Google has rolled out a smallish update for their Google Voice mobile app for the Android devices.
The updated version fixes the crashes on Android 4.2 devices. There are two other enhancements listed:
Now integrated with Android 4.0 visual voicemail.
Direct access to folders from the inbox in Android 4.0.
Google Voice continues to remain a US only service allowing users to share a single contact number that connects to multiple telephony devices.
