Google has updated Google Voice for Android to integrate with the Android 4.0 dialer, allowing users to view and listen to their Google Voice voicemail in their standard call log. It's the first implementation of visual voicemail we've seen that's based on the ICS API, which Google released to carriers to develop apps for their own individual networks rather than include visual voicemail with the Galaxy Nexus by default. The app also includes an updated UI that looks more holo-like, with a new menu bar at the bottom of the screen. Google's also included the ability to slow down or speed up message playback, which it says will be helpful for focusing on voicemail details or speeding through long messages. To enable the new features, you'll have to download the latest app and check "voicemail display" in Google Voice settings. You can head over to the Google Play Store to grab the update, available now.
