I am buying 5 2g ipod touchs for a variety of age ranges. I would like to "set up" the things for the younger ones. I would be syncing all of them on 1 PC and purchasing a few songs and adding bookmarks etc. My questions; 1) can you change your username with itunes? 2) can you download, purchase with gift cards, directly and using the itouch once an account is created? 3) can you access your account from the itouch? The goal is to be able to allow control of content without access to a computer. Is this possible?
