I can't believe I haven't fiugured this out, but I can't
I was playing around with the X and noticed in the contacts, under the menu there's "Display group" option. There's an option to create a group and I do (Little League) and then I want to add my kid's coaches. But when I menu>add contact it never saves to the group, but rather the "All contacts".
I also tried doing this through the PC and though it works there, after syncing it does not show correctly on the phone.
So how to I create groups of contacts on the phone?
