Okay, so i had my dads friend put a lot of apps onto my ipod touch from his PC. And now i brought it back home and want to put some of my own ipod apps onto my ipod touch. So i have to authorize his apps onto my computer for them not to get deleted once i put mine on right? Well on my itunes, i can't find those apps that i have on my ipod touch. So what do i do now? thanks for the help.
