One of the cool features of google plus mobile app is instant upload i.e upload the pictures or video as you shoot instantaneously to the google+ social network.
We are not sure or have any indication of google+ applications are coming. But we think it would be a critical, important and great feature to compliment unique feature that Google+ offers.
Google+ was released 4 weeks ago in field trial mode and an android app was released immediately. Android smartphone users were the only lucky one’s enjoying Google+ from their mobiles.
