Editors' rating: 7.7, very good

The good: The HTC Cavalier S630 improves on its predecessor by adding 3G support, a faster processor and a 2-megapixel camera. It comes out of the box with Windows Mobile 6, push e-mail, integrated Wi-Fi and Bluetooth.

The bad: The new "Joggr" control is temperamental, and the Cavalier S630's QWERTY keyboard is smallish. Speakerphone quality also could be better. Also, we wish the camera included a flash.

The bottom line: Though we're not particularly keen on the design changes, the HTC Cavalier S630, with 3G support and a more powerful processor, is a worthy upgrade to the T-Mobile Dash. Mobile professionals will be well-served by this smart phone.

Editors' rating: 8.3, excellent

The bottom line: The BlueAnt Z9 is a great-looking headset with outstanding sound quality at a very affordable price.
