it seems that the changed the behavior of the contact "list" on the phone app.
on the Incredible, it would show the call history. Whereas for the TB, it seems to show some amalgum of some call history, then favorites, then your full address book.
the weird call history has my home number (which is under my wife's contact), but every time i call her mobile, it does not change the entry to her mobile. it's very weird.
