Ah, sorry not to have replied iRock1. I'm a MacRumors Forum N00B and still parsing all the email notification settings.
Either way, it's still an extra step: Scenario: I have a "Work" group, a "Buddies" group and a "School" group. In iOS <=5, I would press the "Work" group and see all contacts in that group. I could go back and press the "School" group and see all the contacts in that group. Simple, immediate.
In iOS >=6, I can press "All Groups" and see all my contacts. I can press "Work" and see my work contacts. But if I then want to see my "School" contacts, I have to DESELECT "Work" and then select "School." Otherwise, the "Work" group is still selected. To me, an annoying additional step.
The iOS >=6 system introduces the feature of being able to view contacts from two different groups simultaneously, which is nice, I guess. But adds an extra step if I want to only view groups one at a time. (Which is, to me, the whole point of segregating one's contacts-- if I can't remember which group a particular contact is in, I can just search All Contacts)
Oh, well. Too bad Apple doesn't include a feature to allow both ways of viewing contact groups.
Thanks again for your feedback and apologies for the tardiness of my reply.
