This update to the popular Black Jack sports a new spinning jog wheel and GPS.

It also steps up to a larger battery, larger display, more memory, faster data and higher-resolution camera.

The Black Jack II is also slightly heavier (4.1 ounces versus 3.5 ounces) and a tad thicker than its predecessor.

Some may prefer the Moto Q Global's plumper keyboard, but we were able to type on this taller, more compact layout almost as quickly.

Quick-launch keys for the browser, Cellular Video, camera, and e-mail line the bottom of the layout.

What we couldn't do as quickly as we'd like was adjust the volume; the Black Jack II's extra height forced us to slide the device down in our hand to activate the volume keys on the top-left side.

We're also not too keen on the Power button's location on the very top of the device; we'd much prefer that the End key on the front take on this function.

The Samsung Black Jack II, or Samsung SGH-i617, is a smartphone available through AT&T in the United States. Canadian version, SGH-i616 is marketed as "Samsung Jack" by Rogers and Fido.

The phone has since been succeeded by the Samsung Epix. The original Samsung Black Jack was one of our favorite Windows Mobile phones because of all the features it delivered for a low price, including 3G data and support for Cellular Video and XM radio.The Windows Mobile 6-powered sequel sports a sexier design and a lot of other improvements, including a beefier battery, more internal memory, and GPS navigation support.The Black Jack II is a bit slippery for our tastes, and it picked up fingerprint smudges too easily.On the plus side, the bulge on the back of the device beneath the camera made making calls comfortable.The front of the Black Jack II houses a new spinning jog wheel that doubles as a D-pad, which made scrolling through lists and Web pages on the 2.4-inch display simple.
