And it is so unintuitive and obscure that heaps of people have ended up here, including me, as we couldn't figure out how it is supposed to work!!!
Send you feedback to Apple and maybe we can get this changed.

I'm going back to 5.1.1.
This is what I sent
"This new implementation of how to get into groups in Contacts in iOS6 is just ridiculous.
I spent ages trying to work out what was wrong, I restored the software, ended up at the Apple discussion forums and found out how it was supposed to work. Some clever person finally worked out how to work it.
This is so UNINTUITIVE and so UNLIKE any other aspect of the OS that people are flocking to the Apple discussions in droves thinking there is something wrong with Contacts because they do not realise how it is supposed to work.
If you are going to implement weird way out ways of doing things like this then you better start printing out manuals to hand out with the phones, because nobody is going to understand how to use them.
It stumped me and I was an Apple technician in a school for 15 years!!!!
Please, please change this back. You are making it so hard to use for ALL users for what gain?? So the rare individual who wants to view more that one group at once can???
If you really want to view more than one group at once you can create a new group with them all in it."
