Last night the talk of the town centered around an update that started filtering out for our beloved Google Hangouts app. The update moved it to version 2.3 and gave it a bit of an overhaul in the looks department. More importantly though, it added in the long, and maybe way overdue, Google Voice integration that was rumored to be on its way. With the new Hangouts update and GV integration comes a new app as well, Hangouts Dialer.
You will need the new Hangouts v2.3 update to get it to all work. Luckily for you, we have that APK waiting for your downloading pleasure as well over at Gappsearly.com.
