iTunes is easy to use one can create playlists so that your music is managed upload Picts, applications music and movies etc. Further more it backs up your iphone.
Have a look at this link on our iPad forums site. I realize it is for the iPad however the same method applys. I have requested we have a special thread for beginners on this site similar to this one. Also be aware itunes does have a very informative help section in the menus. Hope this helps http://www.ipadforums.net/ipad-faq/3470-ipad-absolute-beginners.html
