TrustedReviews gives us a review on the Samsung SGH-i600 PDA phone (aka BlackJack in the US), which supports HSDPA. The Samsung SGH-i600 is powered by Texas Instruments OMAP 1710 220 MHz processor and runs Window Mobile 5.0 OS. i600 has a 2.3-inch QVGA LCD, a 1.3Megapixel camera, camcorder, MP3 Player, file viewer, and Bluetooth.
It is a shame Samsung was not able to move to Windows Mobile 6 with this smartphone, and I’m not sure it is really sleek enough to fit into the Ultra range. But as a 3G/HSDPA, keyboarded, scroll wheeled smartphone with some good software extras it stands up well.
