If you're a Google Voice user there's quite the update waiting for you in the Google Play store this afternoon. The newest version (0.4.2.54) features tight integration with the Ice Cream Sandwich dialer, a new voicemail option, and the inclusion of labels (think folders) for your inbox. Here's the not-so-fun part -- unless you have a phone with Ice Cream Sandwich, you won't get to see most of it.
All phones will get the inbox labels, which is one thing many folks, myself included, have been waiting for. If you use your Google Voice inbox as a catch-all storage and never delete anything you can now attempt to keep things organized and access it all from your phone. This is the best change for me, but the others are nice as well.
Voicemails are now able to be played through the native Ice Cream Sandwich dialer, just like carrier voicemail. You can adjust the speed to play them faster or slower (handy when skipping to the good part). You enable this in the Google Voice settings, and it's a great way to manage two numbers if that's how you roll. That is how I roll, and it's really handy. Too bad it's ICS only. Hit the break for a couple screenshots of all this, and the download link if you need it.
