Update to Google Voice kills Android 4.2 bug
Google sent out an update to the Google Voice app on Wednesday that clears up the problem. Available at the Google Play Store, Google Voice version 0.4.2.66 does away with those annoying f/c issues and allows you to get your text messages addressed and sent out. Pick up the reworked app for free from the Google Play Store, which you can get to by clicking on the sourcelink.
