If all else fails you could try X-Lite v2.0 released today: http://www.xten.com/lite.php
Side question...
I've got xten lite running on a Dell Axim, and the screen indicates it has logged in to the defined server. However, since the xten image consumes the entire screen, I can't access the Axim keyboard to enter a sip address. (Just purchased the Axim). Anyone know how to bring up the keyboard in order to enter the sip address?
