I recently purchased a Samsung Blackjack and have been playing around with the theme engine built into Windows Mobile 5.0 Smartphone. The theme below requires no special plugins and should work on the Motorola Q and Samsung Blackjack. It was derived off of the Just Black theme found at KOOLdezine Themes and can easily be modified to add additional plugins and change the layout.

Installation Explorer your device using ActiveSync and copy the contents of the zip file to \Application Data\Home\, then set the theme in the display settings.
