RIM BlackBerry Curve 8520 (T-Mobile)

The good: The RIM BlackBerry Curve 8520 features a responsive optical touchpad and dedicated media controls. The smartphone also offers Wi-Fi, Bluetooth, a 2-megapixel camera, and good call quality.

The bad: Lacks 3G support and GPS. You can only save downloaded apps to the phone's main memory.

The bottom line: The RIM BlackBerry Curve 8520 is a sleek entry-level smartphone that delivers some nice design enhancements and great performance. While available directly from T-Mobile, Wal-Mart offers the better value on the smartphone.
