Yeah you can sync using Wi-Fi. Make sure it's checked off in your settings

You'll need to plug it into your computer first and then check "Sync this iPhone wirelessly" or something like that in iTunes. You'll need the latest software (iOS 5 or 6).
Or you can just buy music on the iPhone with iTunes. Less complicated.
