on my iphone, the contact list was just all one list, then one day, i looked at it, and bam it was all like organized, i was just wondering if its possible to switch it back, or that did that happen because of an update
you could be more descriptive ... but no that has been there for a while.. If you have your contacts in groups on your computer, then it will sync over in groups..
in the top right corner there should be a button that says groups, touch that and you can change the group you view...
