Google+ for Android and iOS got updates. Now you can hangout right from your Android (Ver 2.3 +) or iPhone. I have tried Google Plus hangout on iPhone with Srivatsan. The Audio and video quality is good, Since I tried over WiFi Connection. You can also do hangouts on 3G network.
You can join hangout if some one invited you.. Here are some images from my iPhone
Do you like the new hangout feature for your iPhone ?
