My favorite is Samsung Chat 322. It's Edge for data, but both Sim Cards are quadband. Plus you have exchange to sync your mail and contacts among other features, plus "qwerty" keyboard.
Seems to me Nokia its behind, even been good phones.
Update: Since this post Samsung has announce two new "dual SIM Phones" with Android and WiFi, will review the model with "keyboard" should be available in the first quarter of the year.
