As expected, Cingular has announced availability of the Samsung BlackJack, a thin QWERTY smartphone set to compete with the Motorola Q and T-Mobile Dash. The BlackJack, also known as the SGH-i607, is a Cingular exclusive and is also one of only a few HSDPA compatible handsets in their lineup. Size wise it’s comparable to the Q and Dash, though it’s relatively light compared to either.

Features of the Samsung BlackJack include:

• Quad-band GSM plus HSDPA and EDGE data
• Just 12mm thick
• QVGA display
• Windows Mobile 5.0
• 1.3 megapixel camera
• Stereo Bluetooth
• microSD card slot

Cingular will begin selling the BlackJack this week for as low as $199 after rebate with a 2-year contract including unlimited data. That matches the price point of the Q and Dash (though their contract requirements are not as expensive).
