I'm just trying to remove the Launcher2.apk file that I moved to the /system/app folder. Everytime I try to delete the file or uninstall it, i get this problem: "Warning: Launcher2.apk cannot be deleted because the file system is read-only." How do i just get rid of this file already?? EDIT: Never mind. Someone helped me (Thanks gotta have that funk). The answer in case anyone else is having the same trouble as me: "in root explorer, hit mount r/w at the top right. then delete it." voila.
