sync music with a iPhone 4 iOS 6

Is there any way to sync an iPhone iOS 6 with my PC? I installed libimobiledevice and the iPhone is shown up in Rythmbox and Shotwell. But when i want to sync music with it, it doesn't work. There will be no music on my device. Please help.

It is not yet possible to sync with devices on iOS 6.x.x. In fact, libmobiledevice still does not support syncing with iOS 5.x.x

If you are using iOS 5.x, the library that Rhythmbox (and others) use to do this does not yet support the newer database version. If your iOS device has recently been updated, then you simply need to wait for libimobiledevice to be updated (watch the [website][1] under Music/Video Synchronization Status for updates).

Have you tried Spotify? I'm using it to sync music with my iphone (iOS 5)...

Edited in response to Eliah Kagan's request below:

Follow the instructions at this link or as copied from it below:
http://www.spotify.com/uk/download/previews/

1. Add this line to your list of repositories via the software settings dialogue

   deb http://repository.spotify.com stable non-free
   

2. If you want to verify the downloaded packages, you will need to add our public key

   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 94558F59
   

3. Run apt-get update

   sudo apt-get update
   

4. Install spotify!

   sudo apt-get install spotify-client
   

Install the Spotify app via the iPhone app store on the iPhone and create a Spotify account (free).

Follow the instructions in Spotify to add your local music folder and then to connect your iPhone - briefly: open the spotify app in Ubuntu and on the iPhone, make sure you are signed in to your Spotify account on both devices and they should connect automatically over wifi. Sync music. Enjoy.

Currently the ogg format is not supported. I have added myself to the request for it here:
