New (LTE) Rotary Cell Phone [video]
Very cool.My only nit is the local/nonlocal/alt switch is unnecessary. Local & nonlocal numbers have a different number of digits. Checkdown logic can determine which it is. The phone book certainly has less than 7 digits of pages, and less than 7 digits of contacts per page. The only issue is determining if a short number is for a contact or a contact page. That can be dealt with by pressing a different button than the call button if it's a page navigation.
