Google voice just got a small, but nice, upgrade, adding direct integration with Android 4.x Ice Cream Sandwich. This allows you to grab any Google Voice voicemails right inside the visual voicemail view of your ICS device, without having to jump back to the Google Voice app.
Previous to this update, you could get your Google Voice voicemails in a nice ‘visual voicemail’ interface inside the app itself. This upgrade now lets you see those voicemails in the standard ICS interface instead, so you don’t have to jump back and forth between apps.
Your voicemails will appear alongside your outgoing, incoming, and missed calls in your phone’s call log and you can just simply touch them to play them. You can slow down the playback of the message which is great for when someone is telling you their callback number, or you even speed playback up, so you can quickly listen to longer messages.
You can grab the latest version of Google Voice right from the Google Play store or just grab the upgrade.
