The Samsung BlackJack i607 simply looks and feels fantastic. The high speed data in 3G coverage areas is wicked fast and voice quality is excellent. The keyboard is excellent, though the number keys are a bit eccentric. We love the jog wheel and most everything about this phone. The camera takes better than average photos, Bluetooth stereo sounds great and Cingular Video is addictive.

While several phones have been billed as potential Q-killers this year, the Samsung BlackJack is the only one that actually is a Q killer. Why? It's on even ground for high speed data (Verizon has a larger coverage blanket at the moment but Cingular has better speeds) and like the Moto Q, the BlackJack looks like a slick, business device. The BlackJack boasts better ergonomics, better speed, better looks, better Bluetooth, a better camera and similarly anemic battery life (but the Samsung wins because it comes with a 2nd battery and charger module for that battery). Maybe the Q will look better in black-- we hear the Verizon Q will soon be black to compete with the Dash and BlackJack no doubt.
Why did the BlackJack earn 1/4 star more than the Dash? They're both excellent phones, and it's not an easy choice. But Cingular's much broader coverage and 3G network influenced our rating, as did the BlackJack's better ergonomics (other than d-pad and surrounding buttons). The BJ is narrow enough to use one-handed even if you have small hands, the jog wheel with action button and back button are awesome as are the totally normal volume controls. The Dash's JOGGR strip in comparison makes us want to scream, yet without it there's no easy way to control volume in call. The BJ's value added software bundle is useful and generous, while the Dash doesn't give you much beyond the basics. You need not disassemble the phone to access the MicroSD card slot.
Pro: Great looks, great ergonomics (other than the d-pad and immediate surrounding buttons). Super-fast data speeds on 3G and excellent call quality. Louder than many other GSM phones. Very good speakerphone. Good bundled software: useful apps that would cost around $100 if purchased separately. Cingular Video support is very cool. Better than average smartphone camera, strong Bluetooth, sharp display and well-spaced keyboard. The jog dial with integrated action key is excellent and we like the hardware volume controls.
