This is a modification of the Pandora app to no longer have that annoying inactivity timeout.
You will likely have to remove the pandora.apk/.odex from /system/app/ for this mod to install properly
NOTE/Warning: Removing .odex files from a non-deodexed system can have UNEXPECTED results.

This should work on any Google TV system. However it is as yet only tested on my NSX-46GT1.
