Hey AAPL, you're on version 6 of your mobile OS already.
And you still CANNOT create/edit Contact Groups natively on iOS.
You need to log-on to iCloud.com (on a normal browser, mobile browser is just a landing page) to create / edit Contacts groups.
Meanwhile, Contacts on OSX has Smart Groups (similar to iTunes Smart Playlists) very useful but they don't sync to your iOS device via iCloud.
AAPL should STOP or LESSEN this skeumorphism bullshit and enable Contact groups creation and editing natively on iOS. Also they should enable Smart Contact Group sync to iOS.
In short make things more useful before you make them look like real world things (skeuomorphism)
