I have several people set up in my Favorites category in the People widget. But when I click them, it tells me "Call not sent. No Valid Number Entered." Ok, I go into people, into the contact, hit menu, More, Set widget action, and attach a phone number. It works for a random amount of time, then returns to "Call not sent. No valid number entered." It does this for all of my contacts and makes the people widget virtually useless for me. Any ideas why it might be doing this?
