You'll need at least iOS5 to be able to use iCloud:
iCloud stores your music, photos, apps, contacts, calendars, and more, and wirelessly pushes them to your devices with iOS 5 or later installed, and to your computers. iCloud is integrated with your apps, so everything happens automatically.
You can only connect to iTunes on your computer to sync content.
But you can download purchased media again for free:
If I understood you and the FAQ articles you so kindly linked to for me, I should be able to download to iPod from iTunes Store, any music I have previously purchased using my netbook. I have not been able to do so yet. First, I had paid using Paypal and was told when using the iPod that Paypal was not allowed for the iPod. So I went back from the netbook and registered a card instead. Now when I use the Ipod and connect to the iTunes Store via DSL, the purchased button only allows me to see the album that I purchased using iPod and that card but not the 15 songs I purchased more recently using the netbook and my Paypal account. Is there a fix for this or is it impossible because of the changes in payment methods?
Thank you so much, your info and links have been very helpful. If I can't download from the store, I will study up and see if I can learn how to use the USB cord to connect the iPod to the netbook and transfer using iTune software.
Only songs you have purchased using iTunes and the iTunes Store can be downloaded again. You can also see your purchases if you log into your iTunes account in iTunes on your computer:
If you bought songs from other sources, you'll have to add them to the iTuens library, in order to sync them to your device after that.
