does anyone know where i can get themes for it?

Many places.

http://forum.xda-developers.com (look in the Excalibur section, thats what the Dash is, a branded HTC Excalibur)
http://www.kooldezine.com/Q.htm (most - Windows 6 - Motorola Q themes work very well)
http://www.ekopapers.com/os.htm (my personal favorites, you will need plugins - like Facade - for most of these themes)
http://forums.sbsh.net/index.php?s=425d7af1181e87a433cc590f79192178&showforum=57 (the creators of Facade, all of the themes here require Facade, its worth the purchase cause Facade really makes your Home Screen special).

thanx .
