So I got this working on my sprint touch pro2. Here are a couple pointers:
use the VGA + IVAN1 + SC Pandora cab from here:
http://forum.xda-developers.com/showthread.php?t=534319, (this one has the shortcut included) That gets you up and running. But the songs cut off so you need to adjust the TCP window. You can do like they have been in this thread and install .NET 3.5 and advanced config 3.3 OR just use a reg editor and change HKLM > COMM > Tcpip > Params > Tcpwindowsize to
98304 from 415030. Thats easier than installing the other programs to change one thing. Also note you will have to use the menu button on the pandora app to close the program because the X does not. Good luck
