My favorite phone right now is the Blackberry Curve (8320). I'm coming from a Treo 750 (Windows Mobile) and the Blackberry OS is such a pleasure to deal with after having to deal with the constant resets, freezes, and bugginess of WM. I used to love WM because of all the customization and programs I could download....now I realize that simplicity was what I really needed all along. It's nice to have a phone that "just works".
