At the annual CTIA wireless show in Las Vegas today, AT&T announced plans to launch the Samsung Propel Pro -- a QWERTY slider smartphone running Windows Mobile 6.1 -- this Wednesday. 
Evolving from the popular Samsung Propel handset, the Propel Pro is a silver and chrome compact smartphone with a sliding QWERTY keyboard design.
It features Windows Mobile 6.1 to allow users to run applications on the same platform they use to text and send photos.
It also integrates Wi-Fi and a 3.2-megapixel camera.
The Samsung Propel Pro will be available in April for $150.
