I updated it without reading the forums and reviews, since it automatically appeared in my N9's software update. Downloaded it, rebooted, got that weird red text about "Rescuing update blah blah blah", logged back in with GTalk working fine. Did a video call with a friend of mine. I was using my N9, he was using Gmail. Pretty awesome. However, I noticed the red exclamation mark beside the Gtalk entry in Manage Applications. It says the update failed, etc, despite it operating as expected through GTalk. I guess we all have different experiences with the update, and I'm thankful mine didn't totally F-up my phone. Also noticed that when I went to the app store, it indicates that I don't have Gtalk installed. Maybe there was a corrupted registry entry or something, but I can say right now that it is working as expected. I don't want to uninstall/reinstall it now, as it my screw something up. I am just going to wait for an update to the update. So if you still have the first version, don't update just yet.
