Sorry if this has been covered ad nauseum, but I am pretty confused about iCloud and wifi sync. In iTunes, I selected "backup to iCloud". Does this mean that I won't have any backup on iTunes anymore? And I'm only using 0.8 GB on iCloud, so what exactly is backed up? I know your music purchased on iTunes isn't included in that amount, so I'm assuming that would allow me to backup all my settings, apps, contacts, and iTunes-purchased music? So if I needed to restore my non-iTunes music, I would still need my iTunes backup? So I should be backing up to both iCloud and iTunes? And then there's iTunes match for $25/yr, but do I also need to purchase additional storage space on iCloud? Or does that $25 cover storage space for any mp3 that iTunes can match? If so, what would I need to purchase additional iCloud storage space for? And if I no longer need iTunes, then what's the purpose of wifi sync? Wouldn't I just backup to iCloud?
