I downloaded App INstaller because it recomended using it to install Z4Root. Now that it is installed I was looking at it and it leads me to believe it installs apps only from my SD card. Is this the only place it does it from? It also supposedly can backup apps and also uninstall apps. I guess my question is once I install programs on my X do I need to keep 117 apps that it lists are on my SD card? All my programs are installed in memory on the X itself.
