While we had recently gotten word that the Samsung Propel Pro would hit AT&T March 19th, new announcements confirm that it will instead ship in April for about $150.

The Propel Pro sports a design not common to the current handset market, it has a slideout QWERTY keyboard along with a small joystick used as a pointing device. This compares with things like the Blackberry’s trackball, you get the idea.

Other than that, the Propel Pro will feature a 2.55-inch screen (no touch, sorry), GPS, WiFi, HSDPA, and EDGE. Coupled with Windows Mobile 6.1, a 528 MHz processor, a 3MP camera, and a battery for talk time up to 6.5 hours, the Propel Pro is sure to spurr at least some interest.
