Use Google Talk with multiple accounts
I always use two Google accounts. One for personal use, and the other for professional-related things. On my phone, I have Android 2.3.4 installed (not rooted). I heard that multiple users have been enabled for Honeycomb's Google Talk app. I need that same feature for my phone but I can't seem to find the latest Google Talk app on the Play Store in order for me to update the one that came with my phone. What should I do?
Note: Google Talk's I need the voice calling feature as well.
