We have 5 smart phones in the family, 3 of them are iphones. Those of us on iphones do enjoy the group chat feature between us. By the end of the year, we will have 1 additional iphone and I am getting a Note 2. Preparing for this eventuality, I did not want to be left out in the cold, so I am going to have everyone install ChatON. It is available for ios and android, has group chat and lots of other stuff.
