OK folks, thanks.
I have a SGT so when I requested the app from my PC the app for download did show up on the SGT. So I assume I can grab that file and sideload it to the KF.
I would have to look in the SGT's download folder I assume and then copy to my PC and then to the KF. If that is how it works, what folder/directory on the KF do I copy it to?
