Now I have windows 7 but I thought this would be the best place to ask this question. I recently updated itunes to the latest version but I cannot drag apps onto of each-other to make folders and I do not see an icon called books in the library section to which to put pdfs in. I have an Iphone 3g. Now I was under the impression that with the new iphone os4 update you could read books on your iphone and I didn't read in the wiki that the ibook shelf wasn't coming to the iphone 3g so..... any ways, I tried re-installing itunes to no avail. it sais its 9.2 but it doesn't have these features.... I assume this a mac thing only?
