See Howard is trying to get you to install something again. After looking at it your right my info was bad. It's still possible just not setting a default tone for a group and add a person to the group and you're done. With groups that you've already made its super simple, from group view, just like in your pic, select the group, select the people individually and scroll to the bottom of their contact info (if they're just numbers and an email scrolling won't be necessary), and the findings option should appear with a drop down, and it should be pretty quick and easy to match the tone for those in that group. Then, obviously, it would have to be done for each group this way. I really only have two groups, one and a half, that I care what their ring is so for me is not that big a deal. Of course if you download an app you're going to have to go through some kind of setup process and settings and who knows. I'd guess this would still be faster and no worries that it won't work with anything installed on your phone, and nothing else to install to make it work.
