How do you do this? I've got my son an Ipod touch for Christmas too. I purchase the apps on my Ipod touch and they automatically download.
I never buy anything via my ipod touch only via my PC which I have loaded itunes. My entire library is on there and automatically downloads to my pc. Then when I hook up my ipod to charge it the song and apps will sync to my ipod. This way I always have a back up of what I've bought either on the ipod or on the PC.
