Using an iPhone without a PC?

Ok, so I was looking into buying an iPhone, but my PC broke ages ago, and I know that you need to sync an iPhone for music ect. So I was woundering, is it possible to use an iPhone as normal without the use of a PC at all? I don't really need music, so there's nothing I need to sync for.

Yes, you can sync to the cloud for free. It will sync and backup what's on your phone.

All you need to do it allow it to do so from the settings app on your phone.
